Question

stone dropped from a height of 10 cm above the top of the window of 80 cm high( top to bottom ).Find the time taken by the stone to cross from the top to bottom of the window.

Answer 1

h=0.5gt^2 , where:

g = acceleration due to gravity = 9.8 m/s^2

t = elapsed time

so given the elapsed time to reach the ground was 10 s:

h =0.5*9.8*10^2 = 490 m

So the height of the tower is 490 meters.
