As shown in the figure below, two blocks (m1 and m2) are each released from rest at a height of h = 4.63 m on a frictionless track and when they meet on the horizontal section of the track they undergo an elastic collision. If m1 = 2.50 kg and m2 = 4.25 kg, determine the maximum heights (in m) to which they rise after the collision. Use the coordinate system shown in the figure.   y1f=____m y2f=____m
