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, was $(g = 9.8 ms^{- 2})$

Options:

Answer:

Solution:

For stone to be dropped from rising balloon of velocity $29 m / s, u = - 29 m / s, t = 10 sec .$ $∴ h = - 29 \times 10 + \frac{1}{2} \times 9.8 \times 100 = - 290 + 490 = 200 m .$
