Two pulleys are attached by a rope. The radii of the pulleys are 20" and 7.3" respectively. The larger pulley rotates 30 times in 42 seconds. Find the angular speed of each pulley in radians per second.
***
larger pulley rotates 30 times/42sec= (angular speed of larger pulley)
angular speed is inversely proportional to radii of pulleys
angular speed of smaller pulley=
