You can put this solution on YOUR website! The speed of a point on a circle having a radius of 15 inches is 12 inches per second. Find the angular velocity of the point.
**
Using qualitative analysis method: in=inches, sec=second, rev=revolution, rad=radian, r=radius
angular velocity=(12 in/sec)(rev/2πr in)(2π rad/rev)
in, rev, and 2π cancel out
angular velocity=12/r rad/sec=12/15 rad/sec=4/5 rad/sec
