Salmon often jump waterfalls to reach their breeding grounds. Starting downstream, 3.14 m away from a waterfall 0.517 m in height, at what minimum speed must a salmon jumping at an angle of 27.6° leave the water to continue upstream? The acceleration due to gravity is 9.81 m/s². Answer in units of m/s. A ball is thrown horizontally from the top of a building 87 m high. The ball strikes the ground 66 m horizontally from the point of release. What is the speed of the ball just before it strikes the ground?
