A horizontally moving tennis ball barely clears the net, a distance y above the surface of the court. To land within the tennis court the ball must not be moving too fast.

a. To remain within the court's border, a horizontal distance d from the bottom of the net, show that the ball's maximum speed over the net is

b. Suppose the height of the net is 1.00 m, and the court's border is 12.0 m from the bottom of the net. Use g = 10 m/s² and show that the maximum speed of the horizontally moving ball clearing the net is about 27 m/s (about 60 mi/h).

c. Does the mass of the ball make a difference? Defend your answer.
