(a) During a tennis serve, the ball leaves the server's racquet horizontally 2.5 m above the court surface. What is the required launch speed for the ball to barely clear the net, which is 15 m away and 0.90 m high? (For simplicity, assume the ball travels along the middle of the court, rather than diagonally.) 26.26 m/s (b) How far beyond the net does the ball land? 3.75 m past the net (c) What launch speed would be required to have the ball land on the service line (on the other side of the net)? (Do you see the challenge of serving horizontally with no spin?) x m/s 26.26 2.50 m 15.0 m -7.0 m
