If a wheel is turning at 3.0 rads/s, the time it takes to complete one revolution is about:(adsbygoogle = window.adsbygoogle || []).push({});

3.0 rads/s X 1 revolution/6.28 rads = .477 revolutions/s

now do I just times by 60s to cancel the seconds out to get 1 revolution.

The rotational speed of the minute hand of a watch is:

w= anglular displacement/ time

w=2pi radian in a circle/ 3600 seconds in one rotation --> pi/1800 rad/s

is that right?
