A stone is dropped from a balloon at an altitude of ` 300 m`. How ling will the stone take to reach the ground of (a) the balloon is ascending with a velocity of ` 5 ,s^(-1). (b) the ballon is descending with a velocity of ` 5 ms^(-1)` (c ) the balloon is shationary ?

Explanation

To solve the problem of how long a stone takes to reach the ground when dropped from a balloon at an altitude of 300 m, we will consider three scenarios: (a) the balloon is ascending with a velocity of 5 m/s, (b) the balloon is descending with a velocity of 5 m/s, and (c) the balloon is stationary.

### Given Data:
- Height (h) = 300 m
- Acceleration due to gravity (g) = 10 m/s² (approximate value)

### (a) Balloon ascending with a velocity of 5 m/s
