1. The problem statement, all variables and given/known data Consider a frictionless track. Imagine point A to B is one quarter of a circle; point B to C is a horizontal flat plane; point C to D is also one quarter of a circle. The block m1 is released from A. It makes a head-on elastic collision at B with m2 (that is initially at rest) Calculate the maximum height to which m1 and m2 rise after collision. m1 = 2kg m2 = 10 kg radius of quarter circles = 4.9 m 2. Relevant equations p=mv m1vf + m2vi = (m1 + m2)v y=1/2 at^2 3. The attempt at a solution I am not quite sure how to attempt a solution.
