hershman (cth2583) - Homework 3, 2d motion 23-24 - tejeda - (LorysJPHY1_1) 4 from a cliff 31.8 m high. At the level of the sea, a rock sticks out a horizontal distance of 22 m/s 14.57 m. The acceleration of gravity is 9.8 m/s2. 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, 1.73 m away from a waterfall 0.39 m in height, at what minimum speed must a salmon jumping at an angle of 38.8 leave the water to continue upstream? The acceleration due to gravity is 9.81 m/s. Calculate the distance d she travels along Answer in units of m/s. the incline before landing. Answer in units of m. 019 10.0 points A ball is thrown horizontally from the top of 021 (part 2 of 3) 10.0 points a building 150 m high. The ball strikes the Determine how long the ski jumper is air- ground 59 m horizontally from the point of borne. Answer in units of s. release. What is the speed of the ball just before it strikes the ground? 022 (part 3 of 3) 10.0 points Answer in units of m/s. What is the magnitude of the relative angle with which the ski jumper hits the slope? 020 (part 1 of 3) 10.0 points Answer in units of . A ski jumper travels down a slope and leaves the ski track moving in the horizontal direc- tion with a speed of 22 m/s as in the figure. The landing incline below her falls off with a slope of 0 = 410 The acceleration of gravity is 9.8 m/s2
