The problem involves calculating the magnitude of angular acceleration for a record player that slows down from a rotational speed of 18 revolutions per minute to a stop over a period of 70 seconds. The context is within the subject area of rotational motion and kinematics.
The discussion is ongoing, with participants providing guidance on reviewing foundational concepts and equations. There is an acknowledgment of the original poster's uncertainty and a general exploration of the problem without reaching a consensus or solution.

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.
