A body is projected vertically upwards and attains maximum height H. If the time to reach height 'h' and H are in the ratio of 1:3, then the ratio`h/H` is :

A

`4/9`

B

`3/2`

C

`5/9`

D

`3/2`

Text Solution

Verified by Experts

The correct Answer is:
c
Here let u be the initial T be the total time and t be the time to reach height .h. , then
`t/T =1/3`or T=3t
`=(5ghT^2)/(18)xx(2)/(g t^2)`
=`5/9`
