Chapter 10, Problem 34RCQ

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

1. To remain within the court’s border, a horizontal distancedfrom the bottom of the net, show that the ball’s maximum speed over the net is

$v=\frac{d}{\sqrt{\frac{2y}{g}}}$

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 $g=10m/s^2$ and show that the maximum speed of the horizontally moving ball clearing the net is about 27 m/s

(about 60 mi/h).

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