The displacement of a car is given by the formula: $s=-2t^3+2t^2+16t-1$ where $s$ is in metres and $t$ is in seconds

1. Find the formula for the velocity of the car at any time time $t$
2. Find the acceleration of the car when $t=5$ seconds.

1. v=-6t²+ 4t +16 where v is velocity in m/s and t is time in seconds 2. -56m/s² ( deceleration of 56m/s²)
