The acceleration of gravity is 9.81 mys . |the cheetah catches its prey. What was the cat's speed when it slid off Answer in units of s. the table? Answer in units of m/s. 016 (part 2 of 2) 10.0 points The cheetah can maintain it's maximum speed 013 10.0 points for only 7.5 s. What is the minimum distance the gazelle Given: The battleship and enemy ships A must be ahead of the cheetah to have a chance and B lie along a straight line. Neglect air of escape? (After 7.5 s the speed of cheetah is friction. less than that of the gazelle.) A battleship simultaneously fires two shells Answer in units of m. with the same initial velocity at these two enemy ships. 017 10.0 points Cliff divers at Acapulco jump into the sea from a cliff 37.3 m high. At the level of the 30 m/s sea, a rock sticks out a horizontal distance of 14.79 m. The acceleration of gravity is 9.8 m/s-. With what minimum horizontal velocity must the cliff divers leave the top of the cliff if they are to miss the rock? Answer in units of m/s. 018 10.0 points Salmon often jump waterfalls to reach their breeding grounds. Starting downstream, 1.98 m away from a waterfall 0.613 m in height, at what minimum speed must a salmon jumping at an angle of 34.2' leave the water to continue upstream? The acceleration due to gravity is 9.81 m/s Answer in units of m/s. 019 10.0 points A ball is thrown horizontally from the top of a building 110 m high. The ball strikes the ground 66 m horizontally from the point of Calculate the distance d she travels along release. the incline before landing. What is the speed of the ball just before it Answer in units of mi strikes the ground? Answer in units of m/s. 021 (part 2 of 3) 10.0 points Determine how long the ski jumper is air- 020 (part 1 of 3) 10.0 points borne. A ski jumper travels down a slope and leaves Answer in units of s. the ski track moving in the horizontal direc- tion with a speed of 30 m/s as in the figure. 022 (part 3 of 3) 10.0 points The landing incline below her falls off with a What is the magnitude of the relative angle slope of 0 - 56. with which the ski jumper hits the slope? The acceleration of gravity is 9.8 m/s. Answer in units of
