A block of mass 4.253 kg is released on
the track at a height 5.52 m above the level surface. It slides down the track and makes a head-on elastic collision with a block of mass 17.012 kg, initially at rest. The acceleration of gravity is 9.8 m/s2 . Calculate the height to which the block
with mass 4.253 kg rises after rebounding from the collision.
