A 2.00 kg rim with a radius of 20.0 cm is setting on an 8.00 kg wedge of angle 30 degrees. The kinetic coefficient of kinetic friction between the wedge and the floor is 0.20

Question

A) With F = 0.00 N, find the minimum coefficient of static friction between the rim and the wedge required for rolling without slipping.

B) Find the minimum force required to keep the rim from rolling downward.

C) Find the maximum force required to get the rim rolling upwards at a constant speed.
