B) A hollow round ball is placed on an incline of angle 30.0°. The coefficient of kinetic and static friction of the incline are jx=0.60 and us=0.80, respectively. The object is released from rest and allowed to roll downhill. 1: Draw a free-body diagram of the object. 2: Derive an equation for the frictional force acting on the object by summing torques. 3: Apply Newton’s 2nd law to calculate the linear acceleration of the object as it rolls down the hill.
