5. [2/7 Points] DETAILS a m Vm PREVIOUS ANSWERS Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them as shown in the figure below. A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of 3m = 2.50 m/s. m J Before wwwwww After 3m V3m SERPSET9 9.P.011. 3m (a) What is the velocity of the block of mass m?
