The Graph Below Shows a Plot of Angular Acceleration in Rad/s2

Multiple Choice

The graph below shows a plot of angular acceleration in rad/s2 versus time from t = 0 s to t = 8 s. The angular velocity at t = 0 s is $\omega_{0}=5 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CCW. The angular velocity, $\omega$ , at t = 8 s is:

A) $18 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CW.
B) $18 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CCW.
C) $23 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CW.
D) $23 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CCW.
E) $43 \frac{\mathrm{rad}}{\mathrm{~s}}$ , CW.
