Two blocks of masses M and 3M are horizontal and frictionless is on the surface. A massless spring with spring constant 96 N / m from blocks attached to one. Compressed between spring blocks and blocks It is tied with a massless rope as shown in the figure. The rope holding the masses has been cut then the 3M block is moving to the right at 2 m / s. In this case after the rope is cut a) What is the velocity of the block of mass M. b) If M = 0.5 kg, how much was the spring compressed before the rope was cut.
