Question

In the table below are listed the initial angular velocity0 and the angular acceleration of fourrotating objects at a given instant in time. In each case, statewhether the angular speed of the object is increasing ordecreasing. and explain your answer.                   0                                  A +12 rad/sec +3.0 rad/sec2 B +12 rad/sec -3.0 rad/sec2 C -12 rad/sec +3.0 rad/sec2 D -12 rad/sec -3.0 rad/sec2 In the table below are listed the initial angular velocity0 and the angular acceleration of fourrotating objects at a given instant in time.

Explanation / Answer

When acceleration is positive the velocity increases. When it'snegative the velocity decreases. That means A and C are increasingand B and D are decreasing.
