The key points include the initial height at 144 feet at t = 0 and when the ball hits the ground at t = 3 seconds. A ball is dropped from a height \ ( h \) above ground. What is the total distance travelled by the ball when it finally comes to rest on the ground?A. 2. It hits the ground and bounces up vertically to a height of h/2. Feb 9, 2019 · Description: A rubber ball is shot straight up from the ground with speed v_0 (kern 1pt). Another ball is thrown vertically upwards from the ground at the instant the first ball is released. By the law of conservation of energy, the total mechanical energy of the system remains constant if only conservative forces, like gravity, are acting. 2 \mathrm {~h}C. Neglecting subsequent motion and air resistance, its velocity v varies with the height h as (see Fig. ) Sep 30, 2024 · The function h(t) = −16t2 + 144 describes the height of a ball dropped from 144 feet. A ball is dropped from the top of a building 59 ft tall. Its velocity upon hitting the ground is v. We assume that air resistance is negligible. Use this information to solve the problem. Nov 19, 2019 · Suppose an object is dropped from a height h0 above the ground. This energy is entirely due to the height from which the ball is dropped. Neglecting subsequent motion and air resistance, describe how its velocity v varies with the instantaneous height y. Now we have the equation of accelerated motion we get V^2 = 2g (h – y) 2gy = 2gh – v^2 y = 2gh – v^2/2g -----------1 So this relation is between v and y. In this problem, the potential energy is given as 50 J. At what height above the ground is the ball's velocity equal to 2v? A. 4h B. When the ball is dropped from height h, it has potential energy and no kinetic energy.
