Several rotating objects are described below. Their angular velocity is

provided along with their angular acceleration. Consider the rate at which the speed of their rotation is

changing. Which object is slowing down at the fastest rate?

A$.$ A disk with z $=2\mathrm{.}00$ rad$/$s and z $=-1\mathrm{.}00$ rad$/$s$2.$

B$.$ A wheel with z $=3\mathrm{.}00$ rad$/$s and z $=-2\mathrm{.}00$ rad$/$s$2.$

C$.$ A ceiling fan with z $=-2\mathrm{.}00$ rad$/$s and z $=-1\mathrm{.}00$ rad$/$s$2.$

D$.$ A flywheel with z $=0$ and z $=-0\mathrm{.}750$ rad$/$s$2.$

E$.$ A circular saw with z $=3\mathrm{.}00$ rad$/$s and z $=-0\mathrm{.}750$ rad$/$s$2.$

Answer: B
