An automobile accelerates from zero to 30 m/s in 6.0 s.The wheels have a diameter of 1.0 m.What is the average angular acceleration of each wheel? A) 5.0 rad/s² B) 10 rad/s² C) 25 rad/s² D) 40 rad/s²

Question

Quizplus · Accepted Answer

The linear acceleration is 30 m/s divided by 6.0 s, which is 5 m/s². The radius of the wheel is 0.5 m (half of the diameter). The angular acceleration is the linear acceleration divided by the radius, which is 5 m/s² / 0.5 m = 10 rad/s².
