A regulation volleyball court is L = 18.0 m long and aregulation volleyball net is d = 2.43 m high. A volleyball playerstrikes the ball a height h = 1.97 m directly above the back line,and the ball's initial velocity makes an angle theta =31^o with respect to the ground (see the figure). Atwhat initial speed must the ball be hit so that it just barelymakes it over the net? (Assume the volleyball is hit so that itspath is parallel to the side-line as seen from an observer directlyabove the court, and that the volleyball is a point object.)

Please show all work. Thank you for your help.
