# Angular Velocity of LP record

## Homework Statement

The once-popular LP (long-play) records were 12 inches in diameter and turned at a constant 33(1/3) rpm.
Find the angular speed of the LP in rad/s and its period in seconds.

1 rpm=((2∏)/60)

## The Attempt at a Solution

for ω i got 3.49

I need help with finding its period in seconds, T.

One of the basic equations of circular motion, well worth knowing!

thank you. could you please let me know if my omega is correct. I just want to make sure. for T i got 1.80

Unless we both made some horrible mistake!

yayy! thanks! on to the next...
