from a cliff 37.3 m high. At the level of the sea, a rock sticks out a horizontal distance of 30 m/= 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.
