How many radians per second is that?

If the disk has a radius of 0.06 m, what is the centripetal acceleration at the edge?

**drwls**, Sunday, September 12, 2010 at 12:25pmTo convert rpm to rad/s, multiply by

(2 pi rad/rev)*(1 min/60 s)

The Greek symbol omega (usually typed as w here) is usually used for rotation rates in radians per second.

Centripetal acceleration is R*w^2, where R is the radius.

You can do the numbers, I'm sure.
