A graphing calculator is recommended.

$($a$)$ Find the average velocity during each time period.

$($i$)1,2$

$c\frac{m}{s}$

$($ii$)1,1\mathrm{.}1$

$c\frac{m}{s}$

$($iii$)1,1\mathrm{.}01$

$c\frac{m}{s}$

$($iv$)1,1\mathrm{.}001$

$c\frac{m}{s}$

$($b$)$ Estimate the instantaneous velocity of the particle when $t=1.$

$c\frac{m}{s}$
