Open-Ended Question. Show your work and upload it for hand-grading as a pdf.

A box with mass m = 1.2kg on an inclined frictionless surface is released from rest from a height h = 1.75 m . After reaching the bottom of the incline the box slides with friction ( μ k = 0.25 ) along a horizontal surface until coming to a rest after a distance d.

1. Draw a free body diagram for the box while it is on the incline. Clearly label all forces with standard names.

2. Draw a free body diagram for the box while it is on the horizontal surface. Clearly label all forces with standard names.

3. What is the kinetic energy of the box at the bottom of the incline?

4. Calculate the distance d the box will travel on the horizontal surface before coming to a rest.

5. How much is the total work done by the frictional force on the box? Explain conceptually why the work is positive or negative.

A 5kg block sits on a wedge (1.5m high and 3m long at the bottom). Another block hangs vertically from a pulley as shown in the diagram. The coefficient of static friction between block m1 and surface of wedge is.4 while the coefficient of kinetic friction is .25. Assume that the pulley is massless and frictionless. Draw a free body diagram for each block. Carefully label each force. Calculate the magnitude of frictional force and find the mass of block...
