Question $27(5$ points$)$

Chapter $10$: In the process of fixing a flat tire, a motorist sets their spare tire, which has a radius of $0\mathrm{.}3$ m $,$ down next to the car, not realizing that they are stopped on a hill. The tire begins rolling down hill, traveling $50$ m before it comes to a stop. If it took the tire $25$ seconds to roll down the hill, what was its average angular velocity while it was rolling?

$0\mathrm{.}6ra\frac{d}{s}$

$2\mathrm{.}0ra\frac{d}{s}$

$6\mathrm{.}7ra\frac{d}{s}$

$8\mathrm{.}3ra\frac{d}{s}$

$4\mathrm{.}4ra\frac{d}{s}$
