A block is released from rest at point A and slides down a curved slope to point B, then continues until it comes to rest at point C. There is no friction from point A to point B, but there is friction from point B to point C. It stops in a time t as it travels from B to C. The vertical height of A is h above point B, and point C is horizontal distance x from point B. write an expression for h
