Question

A body falls freely under gravity from rest and reaches the ground in time t. Write an expression for the height fallen by the body

WhatsApp

Answer

As we know,

h = ut + 1/2 gt2, where,

g = acceleration due to gravity,

t = time

h = height fallen by the body.

Given,

u = 0

Hence, on substituting the values we get,

h = (0 × t) + 1/2 gt2 = 1/2 gt2

Therefore, maximum height attained by the body = 1/2 gt2
