Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m4.99 kg is released from the position shown, at height -5.00 m above the flat part of the track. Protruding from its front end is the north pole of a strong magnet, which repels the north pole of an identical magnet embedded in the back end of the block of mass m₂ 9.70 kg, initially at rest. The two blocks never touch, Calculate the maximum height to which m, rises after the elastic collision m
