Question

A ball is released from the top of a tower of height h meters. It takes T seconds to reach the ground. What is the position of the ball in T3 seconds


A
h/9 meters from the ground

B
7h/9 meters from the ground

C
8h/9 meters from the ground   
loader
D
17h/18 meters from the ground
loader

Solution

The correct option is C 8h/9 meters from the ground   

h=ut+12gt2h=12gT2

After  T3 seconds,the position of ball,

h=0+12g(T3)2=12×g9×T2

h=12×g9×T2=h9 m from top.

Position of ball from ground =hh9=8h9 m.
