Question

Serving at a speed of 170 km/h, a tennis player hits the

ball at a height of 2.5 m and an angle θ below the horizontal.

The service line is 11.9 m from the net, which is 0.91 m high.

What is the angle θ such that the ball just crosses the net?

Will the ball land in the service box, whose out line is 6.40 m

from the net?
