3.4 Exercise 18

Avg difficulty 2.5

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\theta below the horizontal. The base line is 11.9 m from the net, which is 0.91 m high. What is the angle θ\theta such that the ball just crosses the net? Will the ball land in the service box, whose service line is 6.40 m from the net?
