Problem 4-16 - Projectile - (C)
A tennis player serves a ball horizontally, giving it a speed of \(24\; m/s\) from a height of \(2.5\; m.\) The player is \(12\; m\) from the net and the top of the net is \(0.90 \;m\) above the court surface.
(a) How long is the ball in the air, assuming it clears the net and lands in the other court?
(b) How far horizontally does the ball travel?
(c) With what velocity does the ball strike the court surface?
(d) By how much distance does the ball clear the net?
The direction of \(x\) is counter-intuitive and although not "wrong" is not the best choice.
