Question:
Two carts are connected by a loaded spring on a horizontal, frictionless surface. The spring is released and the carts push away from each other. Cart 1 has mass M and Cart 2 has mass M/3. 1) Is the momentum of Cart 1 conserved?  Yes  No  It depends on M!  2) Is the momentum of Cart 2 conserved?  Yes  No  It depends on M!  3) Is the total momentum of Carts 1 and 2 conserved?  Yes  No  It depends on M!  4) Which cart ends up moving faster?  Cart 1  Cart 2  They move at the same speed!  5) If M = 6 kg and Cart 1 moves with a speed of 16 m/s, what is the speed of Cart 2?  please explain each
