A round object with a diameter of 0.25 m weighing 50.0 Newton starts from rest at the top of a 15.0 m long incline that makes an angle of 38.0o with the horizontal. The moment of inertia is given by I=0.450MR2.
a. Find its velocity at the end of the incline?
b. Determine how long will it take to reach the end?
