A student moves a box across the floor by exerting 23.3 N of force and doing 47.2 J of work on the box. How far does the student move the box?

The speed of a bobsled is increasing because it has an acceleration of 2.0 m/s2. At a given instant in time, the forces resisting the motion, including kinetic friction and air resistance, total 450 N.

A surfer paddles out beyond the breaking surf to where waves are sinusoidal in shape, with crests 59.6 m apart. The surfer bobs a vertical distance of 4.28 m, taking 3.09 s to go from trough to crest.
