A body falls from a height `h = 200 m` (at New Delhi). The ratio of distance travelled in each `2 sec` during `t = 0` to `t = 6` seconds of the journey is.

A

`1:4:9`

B

`1:2:4`

C

`1:3:5`

D

`1:2:3`

Text Solution

Verified by Experts

The correct Answer is:
C
Distance in 1st 2 sec
Distance between 2 sec to 4 sec
`h_2 = 1/2 xx 10 xx (4)^2 - 20 = 60m`
Distance between 4 sec to 6 sec
`h_3 = 1/2 xx 10 xx (6)^2 - (20 + 60) = 100m`
`h_1 : h_2 : h_3 = 1:3:5`
