we neglect the air resistance acting on the balloon of a volley-ball .A player hits the baloon that is situated at point A and throws it with velocity v0 of magnitude 15m/s making an angle 20(degree) with horizontal. The point A is at a height of H=3m from the ground the net is at D=12m from the player ,the height of the net is H=2.4m. 1)show that the service succeeds 2)A player situated at 2m from the net wants to intercept the balloon. at which height H should he put his hands in the plane of the trajectory of the balloon
