The position (x) of body moving along x-axis at time (t) is given by `x=3f^(2)` where x is in matre and t is in second. If mass of body is 2 kg, then find the instantaneous power delivered to body by force acting on it at `t=4` s.

Explanation

To find the instantaneous power delivered to a body by the force acting on it at \( t = 4 \) seconds, we can follow these steps:

### Step 1: Identify the position function
The position \( x \) of the body is given by the equation:
\[ x = 3t^2 \]
