A balloon starts rising from the ground with a constant acceleration of `1.25m//s^(2)`. After 8 s, a stone is released from the balloon. Find the time taken by the stone to reach the ground. (Take `g=10m//s^(2)`)

Explanation

To solve the problem step by step, we will follow the outlined process:

### Step 1: Calculate the height of the balloon after 8 seconds
The balloon starts from rest and rises with a constant acceleration. We can use the equation of motion:

\[ s = ut + \frac{1}{2} a t^2 \]
