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.
Part a) Write an expression for the speed of the block vB at point B. Your answers should be in terms of x and t. (Use equations of 1D kinematics)
Part b) Write an expression for h. Your answer should be in terms of x, t, and g (9.81m/s^2) Apply the work-energy theorem to the block's motion from A to B
