The lob in tennis is an effective tactic when your opponent is near the net. It consists of lofting the ball over his head, forcing him to move quickly away from the net (as shown in the figure below). Suppose that you loft the ball with an initial speed of v = 13.0 m/s, at an angle of θ = 50.4° above the horizontal. At this instant your opponent is d = 11.4 m away from the ball. He begins moving away from you 0.300 s later, hoping to reach the ball and hit it back at the moment that it is h = 2.03 m above its launch point. With what minimum average speed must he move? (Ignore the fact that he can stretch, so that his racket can reach the ball before he does.)

Chapter 03, Problem 77 The lob in tennis is an effective tactic when your opponent is near the net. It consists of lofting the ball over his head, forcing him to move quickly away from the net (see the drawing). Suppose that you loft the ball with an initial speed of 15.0 m/s at an angle of 50.0° the horizontal. At this instant your opponent is 10.0 m away from the ball. He begins moving away from you 0.26 s...
Suppose that you loft the ball with an initial speed of v = 16.0 m/s, at an angle of θ = 48.5° above the horizontal. At this instant your opponent is d = 11.3 m away from the ball. He begins moving away from you 0.400 s later, hoping to reach the ball and hit it back at the moment that it is h = 2.01 m above its launch point. With what minimum average speed must he move? (Ignore...
Suppose that you loft the ball with an initial speed of v = 15.2 m/s, at an angle of θ = 49.2° above the horizontal. At this instant your opponent is d = 10.0 m away from the ball. He begins moving away from you 0.250 s later, hoping to reach the ball and hit it back at the moment that it is h = 2.09 m above its launch point. With what minimum average speed must he move?
