# Torque and Angular Momentum

APPHMC-VXVX13

A $5$ $Nm$ torque acts on a thin hoop with a mass of $500$ $g$ and a radius of $15$ $cm$ for $10$ $s$.

If the hoop starts from rest, what is the new angular velocity of the disc?

A

$666 \cfrac{rad}{s}$

B

$1,300 \cfrac{rad}{s}$

C

$2,000 \cfrac{rad}{s}$

D

$4,444 \cfrac{rad}{s}$

E

$8,888 \cfrac{rad}{s}$
