A body is allowed to fall from a height ...

A body is allowed to fall from a height of `100 m`. If the time taken for the first `50 m` is `t_(1)` and for the remaining `50 s`,is `t_(2)`.
Which is correct?

A

`5:2`

B

`3:1`

C

`3:2`

D

`5: 3`

Text Solution

Verified by Experts

The correct Answer is:
A
`t_(1)`: `t_(2) =(10)/(sqrtg) xx (sqrtg)/(10 (sqrt2-1)) =(1)/(0.4) =(10)/(4) =(5)/(2)` .
