The distance between the base line and the net $($height $0\mathrm{.}9m)$ on a tennis court is $11\mathrm{.}7m.$ In serving the

ball, a player strikes the ball at a position $2\mathrm{.}55m$ directly above the baseline such that it leaves the racket

at a speed of $130k\frac{m}{h},$ parallel to the side lines and at an angle $5$ below the horizontal. Calculate the

clearance with which the ball passes over the net and the distance beyond the net that the ball hits the

surface of the court.
