A wheel rotating about a fixed axis with a constant angular acceleration of $2\mathrm{.}0$ rad$/$s$2$ turns through $2\mathrm{.}4$ revolutions during a $2\mathrm{.}0-$s time interval. What is the angular velocity at the end of this time interval?

a$.$

$9\mathrm{.}5$ rad$/$s

b$.$

$9\mathrm{.}7$ rad$/$s

c$.$

$9\mathrm{.}3$ rad$/$s

d$.$

$9\mathrm{.}1$ rad$/$s

e$.$

$8\mathrm{.}8$ rad$/$s
