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 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 = 1.65 m/s. 3m Before a 3m After (a) What is the velocity of the block of mass m? (Assume right is positive left is negative.) -4.9 v m/s (b) Find the system's original elastic potential energy, taking m = 0.470 kg. Enter a number. is the elastic potential energy transferred after the string is cut? J (c) Is the original energy in the spring or in the cord? • in the spring in the cord (d) Is the momentum of the system conserved in the bursting-apart process? • Yes No (e) If the spring was compressed by 5.30 cm, what is the spring constant of the spring?
