Question

A ball dropped from a window strikes the ground 2.71 seconds later. How high is the window above the ground?

Answer 1

$s=36.52m$

Given ,

Time =2.71 second

We apply the formula

$s=ut+12at^2$

$u=0,t=2.73 \\a=g \\So, the \\height \\ s=36.52m$

When a body is lying on a horizontal surface, the object is subjected to a downward force due to the action of gravity. These gravitational forces always aim to attract the item, confirming the force's nature as an attractive force. Consider an object of mass "M" resting on a horizontal surface; the force exerted to the object by gravity is equal to the weight of the object "W." The acceleration owing to gravity, indicated as "g," is the acceleration by which an object is drawn towards the ground. As a result, Newton's second law states that when the values in the above connection are substituted.
