A block of mass m is pushed up against a spring,compressing it a distance x, and the block is thenreleased. The spring projects the block along a frictionlesshorizontal surface, giving the block a speed v. The same spring projects a second block of mass 4m, giving it a speed of 4v. What distance was the spring compressedin the second case?
