A balloon carrying a stone is moving with uniform speed `5 m//s` vertically upward. At some instant, stone is dropped from the balloon and it strikes the ground after 10 s of its release. The height from which stone was dropped is

250 m

350 m

450 m

None

Text Solution

Verified by Experts

The correct Answer is:

`h=ut-1/2g t^(2)`
`-h=5xx10-1/2xx10xx10^(2)`
`h=450 m`
