An inclined plane is smoothly connected to a vertical loop of radius R. A small body, initially at rest, is released from an initial height H on the plane and then slides down and enters the loop. a) Assume that there is no friction anywhere. What is the minimum height Hmin such that the body remains in contact with the loop at the loop's highest point? b) Now assume that there is friction between the loop and the body with the coefficient of kinetic friction while the inclined plane remains frictionless. What is the minimum height Hmin such that the body remains in contact with the loop at the loop's highest point in this case?
