A body moving in a curved path possesses a velocity 3 m/s towards north at any instant of its motion .After 10s ,the velocity of the body was found to be 4 m/s towards west.Calculate the average acceleration during this interval.

Explanation

To solve the problem, we need to calculate the average acceleration of a body moving in a curved path, given its initial and final velocities.

### Step-by-Step Solution:

1. **Identify Initial and Final Velocities:**
- The initial velocity \( \mathbf{v_1} \) is given as 3 m/s towards the north. We can represent this as:
\[
\mathbf{v_1} = 3 \, \hat{i} \, \text{m/s}
