2. A 2-lb block is released from rest at point A on a track in the vertical plane that forms a circular are with a radius of 6 feet. The coefficient of kinetic frietion between the track and the block µ. = 0.15. What is the normal force acting on the block the instant before it reaches point B at the bottom of the arc? What is the normal force an instant after? This will require integration.
