A stone is dropped from a rising balloon at a height of 76 m above the ground and reaches the ground in 6s. What was the velocity of the balloon when the stone was dropped?

A

`((52)/(3))` m/s upward

B

`((52)/(3))` m/s downward

C

3m/s

D

9.8m/s

Text Solution

Verified by Experts

The correct Answer is:
A
`S= ut + (1)/(2) a t^(2)- 76= 4 xx 6 -(1)/(2) xx 10 xx (6)^(2) rArr u = (52)/(3) m//s`
