Velocity of a particle changes from `(3hati +4hatj)m//s` to `(6hati +5hatj)m//s` 2s. Find magnitude and direction of average acceleration.

Explanation

To solve the problem of finding the magnitude and direction of average acceleration, we can follow these steps:

### Step 1: Identify the initial and final velocity vectors
The initial velocity vector \( \mathbf{v_1} \) is given as:
\[ \mathbf{v_1} = 3 \hat{i} + 4 \hat{j} \, \text{m/s} \]
The final velocity vector \( \mathbf{v_2} \) is given as:
