A uniform solid disk with a mass of $17\mathrm{.}2$ kg and a radius of $0\mathrm{.}663$ m is free to rotate about a frictionless axle. Forces of $90\mathrm{.}0$ and $125$ N are applied to the disk, as the figure illustrates. Taking the clockwise direction to be the negative direction, what is $($a$)$ the net torque produced by the two forces and $($b$)$ the angular acceleration of the disk?

$($a$)$ Number

$23\mathrm{.}21$

Units

$($b$)$ Number

$1\mathrm{.}6\mathrm{.}13$

Units
