Consider a frictionless track as shown in the figure below. A block of mass m1 = 5.95 kg is released from A. It makes a head on elastic collision at B with a block of mass m2 = 10.0 kg that is initially at rest. Calculate the maximum height to which m1 rises after the collision. I need the formula so i can work it out..thanks
