The displacement of the particle is `s = t^4 - 2t^3 + t^2 - t`

The velocity is `(ds)/dt = 4t^3 - 6t^2 + 2t - 1`

The acceleration is `(d^2s)/(dt^2) = 12t^2 - 12t + 2`

Plotting the three on the same graph gives where the displacement is in black, the velocity is in red and the acceleration is in green.
