(e) Is the momentum of the system conserved in the bursting-apart process? O Yes O No (f) Explain how that is possible considering there are large forces acting. This answer has not been graded yet. (g) Explain how that is possible considering there is no motion beforehand and plenty of motion afterward? This answer has not been graded yet.
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 as shown in the figure below. 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 3m = 2.25 m/s. 3m m b m Before wwww After 3m (a) What is the velocity of the block of mass m? (Assume right is positive and left is negative.) m/s (b) Find the system's original elastic potential energy, taking m = 0.500 kg. (c) Is the original energy in the spring or in the cord? O in the spring O in the cord (d) Explain your answer to part (c). This answer has not been graded yet.
