A lead ball is thrown vertically downward with an initial speed of 3.9 m/s from the top of a building, which is 105 m high. (Compare this situation to: A ball is dropped from rest from the top of a building, which is 105 m high. ) The magnitude of the gravitational acceleration g = 9.8 m/s2 Keep 2 decimal places in all answers. In this problem, the following setup is convenient: Take the initial location of ball (the top...
7. A ball is thrown vertically downward from the edge of a bridge 24.0 m high with an initial speed of 12.0 m/s. The ball falls all the way down and strikes the water below. Determine the time it takes the ball to strike the water. 3.75 8. A photographer in a helicopter ascending vertically at a constant rate of 1.2 m/s accidentally drops m above the ground. (a) How long will it take the camera to reach the ground?...
A coin is tossed downward with an initial velocity of 20 meters per second at an altitude of 273 meters. Approximately how long does it take the coin to reach the ground? You will need to use the formula 4.9t2+v0t=s
A pilot flying low and slow drops a weight; it takes 2.4 s to hit the ground, during which it travels a horizontal distance of 180 m . Now the pilot does a run at the same height but twice the speed. How much time does it take the weight to hit the ground?How far does it travel before it lands?
A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s(t)=96t-16t^2a.) at what time will the ball strike the groundb.) for what time t is the ball more than 128 feet above the ground?c.) when will the ball reach its highest peak? how high is it above the ground?
