Two rubber balls with two different masses are dropped from height of 9 meters from rest (neglect air resistance and assume the rubber balls are small in size so they both start at 9 meters above the ground). The more massive ball of 2.2 kg is below the less massive ball of 0.5 kg. The 2.2 kg hits the ground first and collides with the Earth (which is at rest) in a perfectly collision. Then, just above the ground (say at the ground), the 2.2 kg ball (after colliding with the Earth and changing its velocity) collides with smaller mass in another perfectly elastic collision. After the smaller mass collides with other rubber ball, to what maximum height above the ground does it reach in meters?
