Question

A ball of uniform mass M=6.00kg and radius R, rolls smoothly from rest down a ramp at angle (theta)=30.0 degrees

(a) The ball decends a vertical height h=1.20m to reach the bottom of the bottom of the ramp. What is the speed at the bottom?

(b) What are the magnitude and direction of the frictional  force on the ball as it rolls down the ramp?
