A block of 1 kg is moving at 3 m/s. It collides with and sticks to a 5 kg mass that is initially at rest. (1.) Find the final speed of both objects, which move together, using the conservation of momentum, and the fact that momentum is mass times velocity. (2.) If we define the kinetic energy as 1/2 m v², how much kinetic energy is lost as a result of the collision?
