A body starts with a velocity `2 hati +3hatj +11 hatk `m/s and moves with an acceleration `10 hati +10 hatj +10 hatk m//s^2`. What is its velocity after 0.2 seconds ?

Explanation

To find the final velocity of the body after 0.2 seconds, we will use the kinematic equation:

\[ \mathbf{v} = \mathbf{u} + \mathbf{a} \cdot t \]

where:
- \(\mathbf{v}\) is the final velocity,
- \(\mathbf{u}\) is the initial velocity,
- \(\mathbf{a}\) is the acceleration,
