Question

A 5 kg block is on a 52◦ inclined plane, where the coefficient of kinetic friction is µk = 0.46. A force of 30 N is applied along an axis parallel to the incline, as shown in the figure. The block is initially moving up the incline at 3 m/s.

F 30 N 52

a) Draw a free-body diagram for the block.

b) What is the acceleration of the block?

c) How far does the block travel before it reaches its highest point?

d) What happens to the block once it reaches its highest point? Draw a free body diagram for this situation and be sure to justify your answer.
