A 0.12-m radius grinding wheel takes 2.1 s to speed up from 2.0 rad/s to 11.0 rad/s.What is the wheel's average angular acceleration? A) 9.6 rad/s² B) 4.3 rad/s² C) 1.6 rad/s² D) 0.33 rad/s²

Question

Quizplus · Accepted Answer

The average angular acceleration can be calculated using the formula: (final angular velocity - initial angular velocity) / time. Here, it is (11.0 rad/s - 2.0 rad/s) / 2.1 s = 4.3 rad/s².
