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 = 16.3 m/s, at an angle of θ = 51.4° above the
horizontal. At this instant your opponent is d = 11.1 m
away from the ball. He begins...
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...

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 = 17.6 m/s, at an angle of θ = 48.3° above the horizontal. At this instant your opponent is d = 11.8 m away from the ball. He begins...
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?
What are the Solutions to Part B of Chapter 2 of Tillery Physics 9th edition.......kinda pointless for you guys to only have the solutions that the book has already. 1. What was the average speed in km/h of a car that travels 400.0 km in 4.5 h? 2. What was the average speed in km/h of a boat that moves 15.0 km across a lake in 45 min? 3. How much would a 80.0 kg person weigh (a) on Mars,...
Instructions for PHY 2048 Problem Set (PSET): (1) Please NEATLY write your name and your solutions. (2) You must use blank 8"x11" printer paper. (3) Begin each problem on a new page, and put your name on each page. Staple your pages together. 4) Only write on one side of the page. (5) You must write up your solutions independently (i.e. don't copy anyone else's solutions), using your own words and thought process. You must show all of your work....
