Question

In an experiment, a heavy ball takes time t seconds to reach the ground when it is released
from the top of the Leaning Tower of Pisa that is of height h m. What will be the position of
the ball t/3 s after its release from the top of the tower?
A) h/9metres from the ground
B) 7h/9 metres from the ground
C) 08h/9 metres from the ground
D) 17h/18 metres from the ground​

Answer 1

Answer:

C) 8h/9

Explanation:

h = 1/2gt^2

h1 = 1/2 g(t/3)^2

h1 = 1/2 gt^2/9

h1/h = 1/9

h1 = h/9

height from the ground = H = h-h1

H = h-h/9 = 8h/9

Answer 2

Answer=(A) h/8 metres from the ground.
