so the speed of the tennis player is irrelevant. anyway i just constructed a right triangle with a hypotenuse connecting the point where the ball is struck and the top of the net, so technically i guess at -8.08 degrees it should hit, so maybe reduce θ to -8? i cant say exactly since the dimensions of the tennis ball arent listed
