Box A is pulled 2 meters when a 3-newton force is applied to it. Box B is pulled 3 meters when a 2-newton force is applied to it.
How does the work done on the two boxes compare?
OA) More work was done on box A.
OB) More work was done on box B.
OC) The same amount of work was done on each box.

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
