Well, if you want to solve the problem it looks like you'll need to review the basics. There are plenty of resources on the web if you search the appropriate terms. You'll be looking for kinematic equations related to angular motion (or rotational kinematics). They're of the same form as those for linear motion (look up: SUVAT), but use angular quantities rather than linear ones.reformedman said:it's been 30 years since college and I was just browsing the net when I found that familiar problem. I seem to recall something about 2 pi related to rads somehow. I'm not really pressed for the solution, was just wondering. Glad I found this forum though, looking around a bit.

Angular acceleration is the rate at which an object's angular velocity changes over time. It is a measure of how quickly an object is rotating or changing direction.
Angular acceleration is calculated by dividing the change in angular velocity by the change in time. The formula for angular acceleration is: α = (ω2 - ω1) / (t2 - t1), where α is the angular acceleration, ω is the angular velocity, and t is the time.
The standard unit of angular acceleration is radians per second squared (rad/s^2). However, it can also be expressed in degrees per second squared (deg/s^2) or revolutions per second squared (rev/s^2).
Angular acceleration and linear acceleration are related by the radius of rotation. The linear acceleration of a point on a rotating object is equal to the product of its angular acceleration and the distance from the axis of rotation. This relationship can be expressed as a = α * r, where a is linear acceleration, α is angular acceleration, and r is the radius of rotation.
The magnitude of angular acceleration can be affected by several factors, including the object's mass, shape, and the torque applied to it. A larger mass or shape will require more torque to produce the same angular acceleration as a smaller mass or shape. Additionally, friction and air resistance can also impact the magnitude of angular acceleration.
