Answer $3.$b $[3/50]$ To find the numerical values of $,a,$ and $T$ :

Take $g=10\mathrm{.}0\frac{m}{s^2},R=10\mathrm{.}0m,m=10\mathrm{.}0kg,$ and $I=10\mathrm{.}0kg*m^2.$

Please do not forget to put the units!!!

$[1/50]$ From Step $5.,$

$=$dots

$[1/50]$ From Step $4.,$

$a=$dots

$[1/50]$ From Step $3.,$

$T=$dots
