on a frictionless horizontal surface a 1.50 kg mass traveling at 3.50 m/s collides with and sticks to a 3.00 kg mass that is intially at rest. This system then runs into an ideal spring of force constant 50.0 N/cm. What will be the maximum compression of the spring? How much mechanical energy is lost during this process? During which parts of the process (the collision and compression of the spring) is this energy lost.
