If `s=2t^(3)+3t^(2)+2t+8` then find time at which acceleration is zero.

Explanation

To find the time at which acceleration is zero, we will follow these steps:

### Step 1: Write down the displacement function
The displacement \( s \) is given by:
\[ s = 2t^3 + 3t^2 + 2t + 8 \]

### Step 2: Find the velocity function
Velocity \( v \) is the first derivative of displacement with respect to time \( t \). We calculate it as follows:
