Compute each part of given problem:
Problem: In a serve, a tennis player hits the ball horizontally. Neglect the effects of air resistance and the diameter of the ball.
Part A: What is the minimum speed required for the ball to clear the 90.0 cm-high net 16.0 m from the server if the ball is "launched" from a height of 2.65 m?
Part B: Where will the ball land if it just clears the net?
