A balloon is rising vertically up with a velocity of 29 `ms^(-1)`. A stone is dropped from it and it reaches the ground in 10 seconds. The height of the balloon when the stone was dropped from it is

100m

200m

400m

150m

Text Solution

Verified by Experts

The correct Answer is:

`h = ut + 1/2 at^2`
`rArr h = -29 xx 10 + 1/2 xx 9.8 xx (10)^2`
= 200m
