A 0.12-m-radius grinding wheel takes 6.0 s to speed up from 2.0 rad/s to 11.0 rad/s.What is the wheel's average angular acceleration? A)5.6 rad/s² B)0.22 rad/s² C)1.5 rad/s² D)0.080 rad/s²

Question

Quizplus · Accepted Answer

The average angular acceleration is calculated using the formula: (final angular velocity - initial angular velocity) / time. So, (11.0 rad/s - 2.0 rad/s) / 6.0 s = 1.5 rad/s².
