Question 848112: The two pulleys in the figure have a radii of 15cm and 8 cm. The larger pulley rotates 25 times in 36 seconds. Find the angular speed of each pulley in Rad/per sec.
I don't know how to even start i'm not sure what formulas to use V=r(W) or what the angular speed formula is. Please help by showing steps so I can do my other similar problems.

------
Larger Pulley angular speed: (25/36)2pi/sec = 25/18 pi/sec = 1.389 pi/sec
-----------------------------
Not sure if the pulleys are independent or if rotation on
one is linked to rotation of the other.
