Question

A ball dropped from a window strikes the ground 2.73 seconds later. How high is the window above the ground?

Answer 1

`36.52 m`

Explanation:

Simply,here the ball fell down due to gravitational force,

So,we can apply `s=ut+1/2at^2` (all the symbols are bearing their conventional meaning)

Given, `u=0,t=2.73` and `a=g`

So, the height i.e `s=36.52 m`
