A car starts from a stop sign and moves along a straight road so its position as a function of time is presented by the following formula $x(t) = at^2 - \beta t^3$, where $a = 1.8 \text{ m/s}^2$ and $\beta = 0.08 \text{ m/s}^3$. Calculate the average velocity of the car from $t = 0$ to $t = 5$ s. Calculate the instantaneous velocity of the car at $t = 0$, $t = 5$ s, $t = 10$ s. Calculate the time it takes for the car to be again at rest. How far from the starting point will the car be at rest? ***Pleas show the steps to convert on 1.8m/s2 and 0.08m/s
