The angular acceleration of a wheel is given in rad/s² by 45t³ - 11t⁴ where t is in seconds. If the wheel starts from rest at t = 0.00 s, when is the next time the wheel is at rest? A) 5.1 s B) 8.4 s C) 6.9 s D) 3.6 s

Question

Quizplus · Accepted Answer

The wheel is at rest when its angular velocity is zero. Integrate the angular acceleration to find the angular velocity function, set it to zero, and solve for t. The correct solution is approximately 5.1 seconds.
