Adolf and Ed are wearing harnesses and are hanging from the ceiling by means of ropes attached to them. They are face to face and push off against one another. Adolf has a mass of 127 kg, and Ed has a mass of 65 kg. Following the push, Adolf swings upward to a height of 0.65 m above his starting point. To what height above his starting point does Ed rise?

    Momentum is conserved.
    M1V1=M2V2

    Now initial veloicty is proportional to the square root of height attained
    (1/2 mv^2=mgh)
    so
    M1sqrth1=M2sqrtH2

    solve for H2.
