On a frictionless horizontal surface a 1.50 kg mass traveling at3.50 m/s collides with and sticks to a 300 kg mass that isinitially at rest. This system runs into an ideal spring forceconstant 50.0 N/cm.a) What will be the max compression of the spring and b) howmuch mechanical energy is lost during this process?
