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 Vam = 1.75 m/s. What is the velocity of the block of mass m? (Assume right is positive and left is negative.) 3m m Before 3m m After

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 = 1.75 m/s. What is the velocity
of the block of mass m? (Assume right is positive and left is negative.)
