Afrala moves due east with a velocity 20 m/s and a car moves due north with a velocity `v_(2)=15m//sec`. Find the velocity of the car as observed by a passenger sitting in the train

Explanation

To find the velocity of the car as observed by a passenger sitting in the train, we can follow these steps:

### Step 1: Define the velocities
- The velocity of Afrala (the train) moving due east is given as \( v_1 = 20 \, \text{m/s} \) in the positive x-direction. We can represent this as:
\[ \vec{v_1} = 20 \hat{i} \]
- The velocity of the car moving due north is given as \( v_2 = 15 \, \text{m/s} \) in the positive y-direction. We can represent this as:
