during a braking test, a car is brought to rest beginning from an initial speed of 60 mi∕hr in a distance of 120 ft. with the same constant deceleration, what would be the stopping distance s from an initial speed of 80 mi∕hr?
The stopping distance s from an initial speed of 80 mi∕hr will be 219 ft.
Here we can define the value t = 0s as the moment when the car starts decelerating.
At this point, the acceleration of the car is given by the equation:
A(t) = -10 ft/s^2
Where the negative sign is because the car is decelerating.
To get the velocity equation of the car, we integrate over time, to get:
V(t) = (-10 ft/s^2)*t + V0
Where V0 is the initial velocity of the car, we know that this is 88 ft/s
Then the velocity equation is:
V(t) = (-10 ft/s^2)*t + 88ft/s
To get the position equation we need to integrate again, this time we get:
P(t) = (1/2)*(-10 ft/s^2)*t^2 + (88ft/s)*t + P0
Where P0 is the initial position of the car, we do not know this, but it does not matter for now.
We want to find the total distance that the car traveled in a 3 seconds interval.
This will be equal to the difference in the position at t = 3s and the position at t = 0s
distance = P(3s) - P(0s)
= ( (1/2)*(-10 ft/s^2)*(3s)^2+ (88ft/s)*3s + P0) - ( (1/2)*(-10 ft/s^2)*(0s)^2 + (88ft/s)*0s + P0)
= ( (1/2)*(-10 ft/s^2)*9s^2+ (88ft/s)*3s + P0) - ( P0)
= (1/2)*(-10 ft/s^2)*9s^2+ (88ft/s)*3s = 219ft

Which of the following is an example of an energy transfer?
Elastic energy becomes kinetic energy as a ball bounces
OA billiard ball collides with a second billiard ball which is initially at rest, making it move.
Elastic potential energy is initially at rest, making it move.
Elastic potential energy is what causes a ball to bounce or rebound because it is transformed into kinetic energy and used to raise the ball back up. However, because some of the ball's energy was transferred to the ground or changed into sound (in the noise it makes upon impact) and heat energy, the ball won't go as high as it did at first (friction with the table). Additionally, even though we cannot see it, the ball alters once it strikes the ground or a table, energy is needed to take shape for a brief period of time.
Because of this, each bounce has a slightly lower height than the one before it. The ball has some kinetic energy when it hits the floor, but some of it is changed, so it loses some of it each time it bounces. After a few bounces, the ball has so little kinetic energy remaining that it stops bouncing.
Thus the correct answer is option A.

Think of the total distance you have covered in your lifetime. Is it
possible for you to move in some direction to reduce this distance to zero
You can move in some direction to reduce this distance to zero if the body remains at rest position.
How distance is zero?The distance can be zero when the object is present at rest position. Distance is defined as the length covered by a body. The distance can also be defined as the length of the path between two points. Displacement and distance are used for the measurement of length covered by a body. There is one difference between distance and displacement which is displacement can be zero but distance cannot be zero until it stops moving because distance is the total path covered by a body but displacement is the shortest distance between two points. If the distance is not covered by a body means the body can't move then the distance will be zero.
So we can conclude that You can move in some direction to reduce this distance to zero if the body remains at rest position.

If a marble is launched out of a cannon, is it in free fall after it has been launched?
Also, how do you know if it is -10 m/s/s or 10 m/s/s for acceleration in free fall?
It is true that as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance). The value of acceleration will be -10 m/s² for upward motion and 10m/s² for downward motion.
What is Free Fall?Free fall is defined as the condition in which the body moves under the influence of gravity alone. In the case of free fall, there is no air resistance.
Given in the question is a marble launched out of cannon.
Yes, as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance) since it moves under the influence of gravity only. As soon as the marble is launched out of the cannon, it will follow a parabolic path. Now, it will move upwards and reach maximum height. From the launch to the maximum height, the marble will move opposite to that of gravity and hence the value of acceleration due to gravity will be g = - 10 m/s². After the maximum height is achieved, it starts to descend towards the ground such that the velocity vector and acceleration vector are both directed in the same direction. In this case, the acceleration due to gravity will be g = 10 m/s²
Therefore, it is true that as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance). The value of acceleration will be -10 m/s² for upward motion and 10m/s² for downward motion.

Explanation:
An object is lifted from the surface of a spherical planet to an altitude equal to the radius of the planet. As a result, what happens to the mass and weight of the object?.
Answer:
SEE below
Explanation:
MASS is a measure of the amount of matter in an object....it will remain the same ....
WEIGHT is a measure of gravitational pull on the object and is inversely dependent on the square of the distance between the two bodies...so weight will be LESS than on the surface of the planet
a parallel-plate capacitor has 2.2 cm × 2.2 cm electrodes with surface charge densities ±1.0×10−6c/m2. a proton traveling parallel to the electrodes at 1.4×106 m/s enters the center of the gap between them.
The distance has the proton been deflected sideways when it reaches the far edge of the capacitor is [tex]1.08 * 10^-3[/tex].
What is parallel-Plate Capacitor:
When two parallel plates are connected across a battery, the plates are charged and an electric field is established between them, and this setup is known as the parallel plate capacitor.
The parallel plate capacitor formula is given by:
C = k∈0 A / d.
Now,
The electric field is, E = sigma/epsilon_{o} = (1 * 10 ^ - 6)/(8.85 * 10 ^ - 12) = 1.129 * 10 ^ 5 * N / C
The force on the proton is (F) = q E = 1.6 * 10 ^ - 19 * 1.129 * 10 ^ 3 = 1.81 * 10 ^ - 14 * N
So, the acceleration of the proton is,
a = F/m = (1.81 * 10 ^ - 14)/(1.67 * 10 ^ - 27) = 1.084 * 10 ^ 13 * m / (s ^ 2)
Time taken to cross the plate is (t) = d/u = (2.4 * 10 ^ - 2)/(1.7 * 10 ^ 6) = 1.41 * 10 ^ - 8
Therefore, the required distance travelled distance is,
d = u t + 1/2 * a * t ^ 2
d = 0 + 1/2 * 1.084 * 10 ^ 13 * (1.41 * 10 ^ - 4) ^ 2
d = 1.08 * 10 ^ - 3 * m
Therefore, the distance is 1.08*10^-3 m
A parallel-plate capacitor has 2.4 cm × 2.4 cm electrodes with surface charge densities ±1.0×10^−6C/m2. A proton traveling parallel to the electrodes at 1.4×10^6 m/s enters the center of the gap between them.
By what distance has the proton been deflected sideways when it reaches the far edge of the capacitor? Assume the field is uniform inside the capacitor and zero outside the capacitor

The reaction force is string pulling on the Nellie when a tether ball in a horizontal circular path over her head .
A reaction force is a force that acts in the opposite direction to an action force. i.e. Newton's third law of motion describes action and reaction forces and the law states that for every action force, there is an equal and opposite reaction force.
There are Newton's three law of motion which can be describe as ,
The first law is can be stated as, an object will not change its motion unless a external force acts on it.
The second law is describe as, the force on an object is equal to its mass times its acceleration. i.e.
F = ma
In above equation F is force , m is mass and a is acceleration on an object.
The third law can be explained as, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Therefore , from the above discussion can be said as Nellie whirls a tether ball in a horizontal circulars path over her head. if the action force is nellie pulling on the string, the reaction force is string pulling on the Nellie.

a group of students prepare for a robotic competition and build a robot that can launch large spheres of mass m in the horizontal direction with a variable speed and from a variable vertical position and a fixed horizontal position x
Gravity is the sole force acting on the body during free fall motion.
The student should launch the sphere at 2v0 because it will land in the 3 point zone at a distance of around 1.41D.
The variables mentioned are;
the sphere's travel distance when thrown from a height, H = D
The speed at which the ball travels to D = v0
The launcher's current available height is H/2.
The available speeds are v0 and 2v0.
Using the formula H = ut + (1/2)gt2, where u is the beginning velocity of the ball's vertical motion, the following is obtained:
H = (1/2)·g·t²
The time it takes for the ball to fall from H is given by t = ((2H/g)).
The length, D = v0 (2H/g),
we obtain when the height is H/2;
t = √(2·H/(2·g)) = √(H/g)
D1 = v0 (H/g) is the distance traveled.
D = (2) v0 (H/g) = ((2)) D1 follows.
D₁ = D/(√2) ≈ 0.71·D
D₁ ≈ 0.71·D
We have at pace 2v0;
D2 = 2v0 (H/g) = 2 v2 v0 (H/g) = 2 v0 (2H/g) = 2D1 1.41D
D₂ ≈ 1.41·D
The 2 point zone is equal to D/2 x D = 0.5 D x D. (This is where position D1 0.71D is placed)
The 3 Point Zone is located at position D2 1.41D and is defined as D x 3D/2 = D x 1.5D.
The student should launch the sphere at the speed, 2v0, such that the ball will land at D2 1.41D, which is in the 3 Point Zone, given that the ball lands at D2, where it is in the 3 Point Zone.
Complete Question -A group of students prepare for a robotic competition and build a robot that can launch large spheres of mass M in the horizontal direction with variable speed and from a variable vertical position and a fixed horizontal position x=0.
The robot is calibrated by adjusting the speed at which the sphere is launched and the height of the robot’s sphere launcher. Depending on where the spheres land on the ground, students earn points based on the accuracy of the robot. The robot is calibrated so that when the spheres are launched from a vertical position y=H and speed v0, they consistently land on the ground on a target that is at a position x=D. Positive directions for vector quantities are indicated in the figure.
When the students arrive at the competition, it is determined that the height of the sphere launcher can no longer be adjusted due to a mechanical malfunction. Therefore, the spheres must be launched at a vertical position of y=H2. However, the spheres may be launched at speed v0 or 2v0.
Question: In a clear response that may also contain diagrams and/or equations, describe which speed, v0 or 2v0, the students should launch the sphere at so that they earn the maximum number of points in the competition.
