What is the acceleration of a 2 kg basketball rolling down a cart with a force of 16 n

An object is dropped from a tower, 400 ft above the ground. the object's height above ground t seconds after the fall is s(t)equals400 minus 16 t squared. determine the velocity and acceleration of the object the moment it reaches the ground. the velocity of the object the moment it reaches the ground is nothing ft/s.

If forces acting on an object are unbalanced, which factors may result fron an unbalanced force? check all that apply
