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 puhed together with the spring between them. A cord initially holding the blocks together is burned; after that happen, the blok of mass 3m moves to the right with a speed of 2.00 m/s.

(a) What is the velocity of mass m?

(b) Find the system's original elastic potential energy, taking m = 0.350 kg.

(d) Explain your answer to part (c).

(e) Is the momentum of the system conserved in the bursting-apart process? Explain how that is possible considering

(f) there are large forces acting and

(g) there is no motion beforehand and plenty of motion afterward?
