A car of mass is initially at rest, and then accelerates at for . What is the kinetic energy of the car at time ?

A man throws a ball straight up in the air at a velocity of . If there is a constant air resistance force of against the motion of the ball, what is the maximum height of the ball?

What is the acceleration of the system shown above? (Assume the table is frictionless and the mass of the rope connecting blocks is negligible).

A car moving at 40m/s suddenly applies a braking force and comes to rest in 20s, with constant deceleration. If the car has a mass of 2000kg, what is the braking force?

If a 15kg object is subjected to a force of 175N to the east and another force of 1020N to the west, what is the object’s acceleration?

A box is placed on a 30o frictionless incline. What is the acceleration of the box as it slides down the incline?

A block slides down a incline. If the coefficient of friction between the block and the incline is , determine the acceleration of the block as it slides down the incline.

Three blocks (in left-to-right order: block A, block B, block C) are pushed along a frictionless horizontal surface by a 50N force to the right, which acts on block A.

If the masses of the blocks are given by , , and , which of the following best describes the relationship between the accelerations of the blocks?
