1. A small block of mass m slides in a vertical circle of radius R on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block’s path, the normal force that the track exerts on the block has magnitude nb. (a) What is the velocity of the block at the bottom of its path? (b) Use conservation of energy to find the velocity of the block at the top of its path. (c) Find the normal force that the track exerts on the block at the top of its path.
