Units A wheel of radius $0\mathrm{.}385$ m $,$ which is moving initially at $\backslash (38\mathrm{.}6\backslash$mathrm$\{$~m$\}/\backslash$mathrm$\{$s$\}\backslash ),$ rolls to a stop in $236$ m $.$ Calculate the magnitudes of $($a$)$ its linear acceleration and $($b$)$ its angular acceleration. $($c$)$ The wheel's rotational inertia is $\backslash (1\mathrm{.}07\backslash$mathrm$\{$~kg$\}\backslash$cdot $\backslash$mathrm$\{$~m$\}^\{2\}\backslash )$ about its central axis. Calculate the magnitude of the torque about the central axis due to friction on the wheel.
