WebThe angular acceleration of all points on the wheel is dω/dt. (d) False. The centripetal acceleration at a point on a rotating wheel is directly proportional to its distance from the center of the wheel 3 •Starting from rest and rotating at constant angular acceleration, a disk takes 10 revolutions to reach an angular speed ω.
The disk starts at $omega_{0}=1 mathrm{rad} / mathrm
