Question

a stone is dropped from the top of the tower of height H if it takes 2.5 sec to reach the ground then the value of His​

Answer 1

Step-by-step explanation:

H = gt²/2 = 10 × 6.25 /2 = 31.25

Answer 2

Given:

Time taken to reach the ground = 2.5 sec

To find:

The height of the tower

Calculation :

From equations of motion, we have

S= ut + (1/2)at²

By substituting the given values, we get

=> H = 0(t) + (1/2)gt²

=> H = (1/2)(9.8)(2.5)²

=> H = 30.625 m

The height of the tower is 30.625 m
