Two blocks are free to slide along the frictionless wooden track shown below. The block of mass m, = 5.07 kg is released from the position shown, at height h = 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 my = 9.60 kg, initially at rest. The two blocks never touch. Calculate the maximum height to which m, rises after the elastic collision. X The equations giving the final velocities in a 1-D elastic collision should prove helpful here. m m
