Question

A stone is dropped from a rising balloon at a height of 91.8 m
above the ground and it reaches the ground in 6 s. What was the
velocity of the balloon just at the moment when the stone was
dropped? ( - 9.8 ms).

​

Answer 1

Answer:

Let the velocity of balloon in upward direction be u.

Thus initial velocity of stone in the upward direction is also u i.e. u

1

=−u

Acceleration due to gravity of the stone a=g=9.8m/s

2

(downward)
