A stone is dropped from a balloon ascending with `v_0=2m/s`, from a height h=4.8 m .Find the time of flight of the stone.

Explanation

To solve the problem of finding the time of flight of a stone dropped from a balloon ascending with an initial velocity, we can break the solution down into several steps.

### Step 1: Understand the Initial Conditions
The stone is dropped from a balloon that is ascending with an initial velocity \( v_0 = 2 \, \text{m/s} \) from a height \( h = 4.8 \, \text{m} \). When the stone is dropped, it will initially have the same upward velocity as the balloon.

### Step 2: Determine the Time to Reach Maximum Height (t1)
When the stone is dropped, it will move upward for a short time until it reaches its maximum height. We can calculate this time \( t_1 \) using the equation of motion:
\[
