1. Block 1, mass m, slides from rest down the inside of a bowl shaped container, starting from a vertical height h. The surface of the container is frictionless. At the bottom, it collides inelastically with Block 2, mass 1/3 m, and the two stick together. To what vertical height does the combined mass slide? Answer in terms of h.
