The Position of a Car Is Given by the Values

question 117

Short Answer

The position of a car is given by the values in the following table.
$\begin{array}{|c|c|c|c|c|c|c|}\hline t \text { (seconds) } & 0 & 1 & 2 & 3 & 4 & 5 \\\hline s \text { (feet) } & 0 & 16 & 35 & 71 & 112 & 179 \\\hline\end{array}$

Estimate the instantaneous velocity when $t = 2$ by averaging the velocities for the periods $[ 1,2 ]$ and $[ 2,3 ]$ .
