cks 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? [-6 m/s] b. Is the momentum of the system conserved in the bursting-apart process? Explain how that is possible considering that there are large forces acting and there is no motion before and plenty of motion afterward? c. If m=2-kg, what is the net impulse acting on mass m? What is the net impulse acting on mass 3m? (-12î kg m/s, 12î kg m/s] M Before 3M M -000000000 After 2.00 m/s 3M
