1. A cat is jumping from a 0.5m table towards a 1.3m table. The tables are 1.2m away from each other. If the cat launches itself at a speed of 6.2m/s 40.0 degree above the horizontal, determine if she will land safely on the table (

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 50.0⁰ the horizontal. At this instant your opponent is 10.0 m away from the ball. He begins moving away from you 0.32 s later, hoping to reach the ball and hit it back at the moment that it is 2.10 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.) Number 15.0 m/s 50.0° Units 10.0 m 2.10 m

QUESTION 8 A projectile is fired from the ground, reaches a maximum height of 37.4 m and lands a distance of 73.9 m away from the launch point. What was the projectile s launch velocity?   A 30.2 m/s, 63.7 degrees above horizontal   B 27.1 m/s, 31.9 degrees above horizontal   C 13.4 m/s, 38.2 degrees above horizontal   D 51.3 m/s, 19.1 degrees above horizontal   QUESTION 9 You launch a projectile toward a tall building, from a position on the ground 35.4 m away from the base of the building. The projectile s initial velocity is 67.5 m/s at an angle of 46.3 degrees above the horizontal. At what height above the ground does the projectile strike the building?   A 76.2 m   B 61.0 m   C 19.2 m   D 34.2 m   QUESTION 10 You launch a projectile horizontally from a building 30.7 m above the ground at another building 49.1 m away from the first building. The projectile strikes the second building 6.4 m above the ground. What…

9. You are a basketball player shooting a three-point shot. You are standing 10.0 m from the basket, which is 3.0m above the floor. You jump up and shoot the ball, releasing the ball when your hands are at the same height as the basket (3.0 m). You release the ball with an initial velocity va, at an angle 0 = 42° from the horizontal. The ball goes in! Your team wins! VA V=0, 3 m + distace 10 m a. What was the initial velocity of the ball?
