A turntable rotates with a constant 2.25 rad/s² angular acceleration. After 4.50 s it has rotated through an angle of 30.0 rad. What was the angular velocity of the wheel at the beginning of this interval?

Jimmothy has a flywheel. It rotates about its central axis. It starts from rest and accelerates uniformly. After completing 100 revolutions, the flywheel reaches an angular speed of 70.9 rad/s. It's your job to calculate the following: 1. What is The angular acceleration of the flywheel 2. What is The time required to complete the first 50 revolutions. 3. What is The time required to complete the second 50 revolutions.

A wheel experiences an angular acceleration of +4.3 rad/s². After making 6.6 revolutions, it has an angular speed of +45 rad/s. What was the wheel's initial angular velocity?

A wheel is initially at rest then rotates with a constant acceleration of 2.0 rad/s2 . What is its angular speed after it has gone through a displacement of 5.0 rad?
