The angle through which a rotating wheel has turned in time $t$ is given

by $=at-b{t}^2+c{t}^4,$ where $$ is in radians and $t$ in seconds.

What is the average angular velocity between $t=2\mathrm{.}0s$ and $t=3\mathrm{.}5s?$

Express your answer using two significant figures.

${}_{\text{a}\text{v}\text{g}}=$

$ra\frac{d}{s}$

Part D

What is the average angular acceleration between $t=2\mathrm{.}0s$ and $t=3\mathrm{.}5s?$

Express your answer using two significant figures.

${}_{\text{a}\text{v}\text{g}}=|,ra\frac{d}{s^2}$
