what is the formula for acceleration?
Answers
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Why was John Paul Jones's victory important in the war? His victory increased France's confidence in the skill of the Continental navy. His victory against a large warship dealt a blow to the Spanish navy. His victory against a superior British foe inspired the American troops.
Answers
Answer:
C. His victory against a superior British foe inspired the American troops.
Explanation:
John Paul Jones is considered the hero in the Revolutionary War. He is known as the Father of the US Navy.
In the Revolutionary War, Jones sided with the American colonists against the British and took hold of naval ships. In 1779, when the British warship Serapis was in conflict with the American warship Bon Homme Richard, Jones plugged the American warship with the Britisher's warship and tossed a grenade into the opponent warship. Thus when Jones was victorious in the war, this boosted the American spirits for the war.

A train reaches a speed of 35.0 m/s after accelerating at a rate of 5.00 m/s2 over a distance of 40.0 m. What was the train’s initial speed?
Answers
Answer:
Initial velocity, U = 28.73m/s
Explanation:
Given the following data;
Final velocity, V = 35m/s
Acceleration, a = 5m/s²
Distance, S = 40m
To find the initial velocity (U), we would use the third equation of motion.
V² = U² + 2aS
Where;
V represents the final velocity measured in meter per seconds.
U represents the initial velocity measured in meter per seconds.
a represents acceleration measured in meters per seconds square.
S represents the displacement measured in meters.
Substituting into the equation, we have;
35² = U + 2*5*40
1225 = U² + 400
U² = 1225 - 400
U² = 825
Taking the square root of both sides, we have;
Initial velocity, U = 28.73m/s

A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles
together. What is the final velocity of the two vehicles?
(Please show work)
Answers
Answer:
50 x 3000 = 150000/4000 = 37.5
37.5 I think.
Explanation:
Hope this helps!
A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.
We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.
The total initial momentum (P_initial) is given by:
P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)
P_initial = (3000) * (50) + (1000) * (0)
The velocity:
Vt = 50 * (1000/3600) = 13.9 m/s
Vc = 0 = 0 m/s
P_initial = (3000) * (13.9) + (1000) * (0 )
P_initial = 41700 kg·m/s
P_initial = P_final
41700 kg·m/s = (3000 kg + 1000 kg) * Vf
41700 kg·m/s = 4000 kg * Vf
Now Vf:
Vf = 41700 kg·m/s / 4000 kg
Vf ≈ 10.43 m/s
Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

1. A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the
table.
A. What is the vertical velocity of the ball just before it hits the floor?
d. What is the horizontal velocity of the ball just before it hits the floor
Answers
Answer:
5.55m/s
Explanation:
The vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
Which type of motion is projectile motion?
Projectile motion is an example of two dimensional motion.
Given is a ball rolls off a 1 m high table and lands on the floor 3 m away from the table.
Using the second equation of motion for the vertical motion -
S = ut + 1/2at²
S = 0 + 1/2at²
S = 1/2at²
t²= 2S/a
t² = (2 x 1)/9.8
t² = 2/9.8
t² = 0.2040
t = 0.451
Now, the vertical velocity of the ball just before it hits the floor -
v = u + at
v = 0 + at
v = at
v = 9.8 x 0.451
[v] = 4.42 m/s
Now, using the second equation of motion for horizontal direction -
S = ut + 1/2at²
S = ut + 0
3 = u x 0.451
u = 3/0.451
[u] = 6.6 m/s
Which is also the horizontal velocity of the ball just before it hits the floor.
Therefore, the vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
