still not getting answer. finding height using work-energy theorem

Question

  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. (you can find a diagram of this by searching up this question, unable to insert image)

Write an expression for h. Your answer should be in terms of x, t, and g (9.80 m/s2). (Apply the work-energy theorem to the block’s motion from A to B.)

Answer 1

Not enough data. You need to know the coefficient of friction from B to C.
