let the angle made with horizontal by 1st body is theta.
so,  the angle made with horizontal by 2nd body is (90 - theta).
h1 + h2 = u2sin2theta/2g +  u2sin2(90-theta)/2g
            = u2sin2theta/2g +  u2cos2theta/2g
            = u2/2g (sin2theta+cos2theta)
            = u2/2g
            = 50 * 50 / 2*10
            = 125......(1)
h1-h2    = 30........(2)
subtacting (2) from (1),
h2 = 47.5 and h1= 77.5
