Aball is thrown horizontally from the top of a building 22.3 m high. the ball strikes the ground at a point 127 m from the base of the building. the acceleration of gravity is 9.8 m/s^2 . find the time the ball is in motion. answer in units of s.

t = 2.13 s

Explanation:

given,

height of the building = 22.3 m

horizontal distance = 127 m

acceleration due to gravity = 9.8 m/s²

time for which ball is in motion = ?

using equation of motion

initial velocity is zero

       t = √4.551

        t = 2.13 s

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
