Two blocks have mass m and M = 3.77m, re-spectively. A light spring is attached to oneof them, and the blocks are pushed together,compressing the spring between them. Theyare secured, in this compressed state, by acord. They are then placed, at rest, on a hor-izontal, frictionless surface. The cord holdingthem together is burned, after which the blockof mass M moves to the right with a speed of2.44 m/s. What is the speed of the block of mass m?Answer in units of m/s.
