A small block of mass m1 = 0.400 kg is released from rest at the top of a curved-shaped frictionless wedge of mass m2 = 3.00 kg, which sits on a frictionless horizontal surface as in Figure P9.60a. When the block leaves the wedge, its velocity is measured to be v1 = 5.00 m/s to the right, as in Figure P9.60b.
(a) What is the velocity of the wedge after the block reaches the horizontal surface?
answer should be in m/s to the left
(b) What is the height h of the wedge?
answer should be in m
