What is the angular speed of a grindstone spinning at 8.3 rev/s?

AI Thread Summary
The discussion centers on calculating the angular speed of a grindstone spinning at 8.3 revolutions per second (rev/s). The formula for angular speed is provided as angular speed = 2π(f), where f represents the frequency in rev/s. Participants express skepticism about the need for a specific book containing this question, suggesting it is a straightforward problem. The search for relevant resources yields limited results, with only three mentions found online. The conversation highlights both the simplicity of the question and the difficulty in locating a specific reference.

Anyone know a name of a book that has question "A grindstone spinning at the rate of 8.3rev/s has what approximate angular speed?"

Why do you need to find this book? This is a basic question, anyone could have made this up on the fly.
 
angular speed = 2pi(f)
f = rev/s

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
