Please answer the question correctly is all I want, dont need to show alot of work just for the final answer to be correct, thanks! Two spheres of mass M1 and M2 are arranged one above the other as shown. They are separated by a negligibly small distance (a fraction of a millimeter). They are released from rest and allowed to fall to the ground, a distance h=5.50 m below as shown. Mass M2 collides elastically with the ground and then elastically with mass M1. And 7.035m is not the correct final answer! Calculate the maximum height in meters to which the center of M1M1 rises above the ground after the collision using the following values: D=0.200 m
