The acceleration of a particle is given by `a=t^3-3t^2+5`, where a is in `ms^-2` and t is in second. At `t=1s`, the displacement and velocity are `8.30m` and `6.25ms^-1`, respectively. Calculate the displacement and velocity at `t=2s`.

Explanation

To solve the problem, we need to find the displacement and velocity of a particle at \( t = 2 \, \text{s} \) given the acceleration function and initial conditions.

### Step 1: Write down the acceleration function
The acceleration \( a \) is given by:
\[ a = t^3 - 3t^2 + 5 \]
