two blocks of masses m and 3m are placed on a frictionless horizontal surface
Ques:
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. 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 2.00 m/s.
(a) What is the velocity of the block of mass m?
(b) Find the system’s original elastic potential energy, taking m = 0.350 kg.
