A delivery truck from the postal service is traveling with constant velocity up an interstate entrance ramp with a 8.0° slope. A 60 kg box sits on the floor of the truck and as a result of static friction, it does not slide. (a) During an interval in which the truck travels 335 m up the ramp entrance, what is the net work done (in J) on the box? (b) What is the work done (in J) on the box by the force of gravity? (c) What is the work done (in J) on the box by the normal force? (d) What is the work done (in J) on the box by the force of friction?

A mouse of mass 200 g falls 100 m down a vertical mine shaft and lands at the bottom with a speed of 8.0 m/s. During its fall, how much work is done on the mouse by air resistance?
Repeat the preceding problem, but this time, suppose that the work done by air resistance cannot be ignored. Let the work done by the air resistance when the skier goes from A to B along the given hilly path be —2000 J. The work done by air resistance is negative since the air resistance acts in the opposite direction to the displacement. Supposing the mass of the skier is 50 kg, what is the speed of the skier at point B ?
