a ramp

Description

A 5.20 kg block is set into motion up an inclined plane with an initial speed of 7.90 m/s. The block comes to rest after traveling 3.00 m along the plane, which is inclined at an angle of 30.0 degrees to the horizontal.

a. For this motion, determine the change in the block's kinetic energy.

b. For this motion, determine the change in potential energy of the block-Earth system.

c. Determine the frictional force exerted on the block (assume to be constant).

d. What is the coefficient of kinetic friction?
