Problem 14DQ

A box slides down a ramp and work is done on the box by the forces of gravity and friction. Can the work of each of these forces be expressed in terms of the change in a potential-energy function? For each force explain why or why not.

Step-by-Step Solution:

Solution 14DQ Step 1: The work done by the gravitational force is W = f.dr Where f = mg sin dr = distance dh = height So, w = mg sin dr We can see dr = dh/sin So, W = mg sin ( dh/sin)
