SUMMARY
In women's volleyball, the net height is set at 2.24 meters, and the endline is 9.00 meters from the net. To determine the minimum initial speed required for a jump serve that strikes the ball at 3.00 meters above the floor and 8.00 meters horizontally from the net, one must apply projectile motion equations. The relevant equations include the horizontal and vertical motion equations, which are x(t) = (1/2)a_x t^2 + v_{0_x}t + x_0 and y(t) = (1/2)a_y t^2 + v_{0_y}t + y_0. By isolating time in the horizontal equation and substituting it into the vertical equation, one can derive the necessary initial speed calculations.
