1. The problem statement, all variables and given/known data There is an object with mass m that travels at constant velocity v. Then it starts to travel up a an incline of mass m2 and angle theta. Find the velocities of both when the block reaches its highest point and what is this highest point. 2. Relevant equations Energy/momentum equations 3. The attempt at a solution This would be a standard question if it werent for the fact that the incline can move. So I am assuming that the object/incline will be one unit and therefore it'll be like an inelastic collision, but I am not sure.
