A particle moves along a straight line such that its displacement s at any time t is given by `s=t^3-6t^2+3t+4m`, t being is seconds. Find the velocity of the particle when the acceleration is zero.

Explanation

To solve the problem step by step, we will follow these procedures:

### Step 1: Write down the displacement function
The displacement \( s \) of the particle is given by:
\[ s = t^3 - 6t^2 + 3t + 4 \]
