Chapter 5, Problem 60PQ
A worker is attempting to lift a 55.0-kg palette of bricks resting on the ground by means of a rope attached to a pulley. a. Before the worker pulls on the rope, what is the force exerted by the ground on the palette? b. The worker exerts a force of 295 N downward on his end of the rope. What is the force exerted by the ground on the palette? c. If the worker doubles the downward force, what is the force exerted by the ground on the palette?

Two objects get pushed by the same magnitude of force. One object is 10x more massive. How does the rate of change of momentum for the more massive object compare with the less massive one? Please be able to explain why in terms of a quantitative statement found in the chapter.
A box is dropped on a level conveyor belt that is moving at 4.5 m/s in the +x direction in a shipping facility. The box/belt friction coefficient is 0.15. For what duration will the box slide on the belt? In which direction does the friction force act on the box? How far will the box have moved horizontally by the time it stops sliding along the belt?
