The volleyball player serves the ball from pt.A w/ an initial Vo at angle theta to the horizontal. If the ball just cleared the net at pt. C and landed on the base at line B.

Determine the value of theta.

Determine the value of Vo.

Determine the time reach to the highest point at the reference from the horizontal surface.

The h from which the ball is thrown is 0.9 m.

I tried solving Vox using Vox = 0.9sin90 by assuming the other angle from Vox to h to be 90 degrees.

I don't know how to get Voy to solve for the theta.
