A balloon is rising vertically up with a velocity of 29 m/s. 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 `(g = 9.8 ms)`

A

100m

B

200m

C

400m

D

150m

Text Solution

Verified by Experts

The correct Answer is:
B
`h = ut + 1/2 at^2`
`rArr h = -29 xx 10 + 1/2 xx 9.8 xx (10)^2`
= 200m
