Homework Help: Physics repost

Posted by Lindsay on Thursday, November 8, 2007 at 6:43pm.

A regulation volleyball court is L = 18.0 m long and a regulation volleyball net is d = 2.43 m high. A volleyball player strikes the ball a height h = 1.76 m directly above the back line, and the ball's initial velocity makes an angle q = 55 with respect to the ground. At what initial speed must the ball be hit so that it lands directly on the opponent's back line?

Would my equation for the x-dir. be Vcos 55*T = 18, since it's the full length of the court?

What would my height for the y-dir. be? Vsin 55*T - (g/2)T^2 = ???
