Two blocks of masses 200 g and 500 g sit on a frictionless table with an essentially massless spring placed between them. They are pushed together until the energy of 3.0 J is stored in the spring. When released, the masses shoot off in opposite directions. What is the speed of the center of mass? What is the speed of the 500-g block?
