```							since initial momentum is 0 final must also be,relative=uhence absolute=u + v...where v=recoil velocity, 4m.v=m(u+v) v=u/3hence initial velocity=u+u/3=4u/3and angle of projection=Ahence Range=  16 u^2 sin2A                        ____________    ANS                             9g RegardsArun (a)skIITians forum expert
