Hey all -(adsbygoogle = window.adsbygoogle || []).push({});

I've got a problem that's rather encompassing...

The second hand and the minute hand on one type of clock are the same length. What is the period T of the motion for the second hand and for the minute hand?

It goes on to say the centripetal acceleration is given by a_c = v^2/r where v is speed and r is the radius. How is centripetal acceleration related to the period?

And then finally it asks for the ratio a_c, second / a_c, minute for the tips of the second hand and the minute hand.

I'm not even sure where to start really...

Any help would be great, thanks!
