Angular Velocity Question!
Hi all, this is my first post, i have a question which is causing me some problems (Headbang) the question is;

a piece of rotating equipment turns through 1770 revolutions in 4 minutes 38 seconds. What is the average angular velocity of the rotating part?

how do i solve this??

Many thanks in advance.

from what i understand the answer is (1770*360)/(4*60+38) deg/sec

i just used the definition of the average angular velocity which is avg $\omega=\Delta\theta/\Delta t$
