Q. A small block of mass m1 = 0.500 kg slides to the left, with a velocity of v1 = -8.40 m/s, towards a curved wedge of mass m2 = 3.00 kg which sits on an icy, frictionless lake surface. When the block reaches the wedge, it slides up to a height 3.00 m above the ice. It comes to a stop relative to the wedge, and the two objects slide together to the left. (a) What is the velocity v2 of the wedge-block system when they are sliding together? (b) Kinetic energy is not conserved during this process. What is the change in kinetic energy?
