A hydrogen balloon is flying eastward with speed ` 12 m s^(-1)` , when wind starts blowing from north to south with speed ` 5 m s ^(-1)` what is the resultant velocity of balloon ?

Explanation

To find the resultant velocity of the hydrogen balloon flying eastward while the wind blows from north to south, we can follow these steps:

### Step 1: Identify the velocities
- The velocity of the balloon flying eastward is \( V_b = 12 \, \text{m/s} \) (in the positive x-direction).
- The wind is blowing from north to south with a speed of \( V_w = 5 \, \text{m/s} \) (in the negative y-direction).

### Step 2: Represent the velocities as vectors
- We can represent the velocity of the balloon as a vector:
