The angular velocity versus time for an object undergoing circular motion is shown in the figure.If the object started from rest at t = 0 s,the net angular displacement of the object at t = t_f is A)in the clockwise direction. B)in the counter-clockwise direction. C)zero. D)The displacement cannot be determined.

Question

Quizplus · Accepted Answer

The net angular displacement of an object is given by the area under the curve of the angular velocity versus time graph. Since the area under the curve from t = 0 s to t = t_f is equal to zero, the net angular displacement of the object is zero, meaning it has not moved from its initial position.
