A box with mass m = 2.2kg on an inclined frictionless surface is released from rest from a height h = 2.35 m . After reaching the bottom of the incline the box slides with friction (coefficient of kinetic friction = 1.2) 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 box of mass m1 = 2.0 kg starts from rest and slides down the frictionless incline. At point A, the box encounters a (massless) spring of spring constant k. It compresses the spring a distance x = 0.25 m to point B where the speed of the box is 4.4 m/s. The first box is then removed and a second box of mass m2 = 3.0 kg is placed on the same incline at the same initial point and...
