A point on the rim of a wheel has a linear speed of 13cm/s. If the radius of the wheel is 40 cm, what is the angular speed of the wheel in radians per second? The answer is .3 radians/sec but I need help understanding how to work the problem.

OpenStudy (isaiah.feynman):

The angular speed is JUST change in angle per unit time.

OpenStudy (anonymous):

How do I find the change in angle though since it gives me linear speed?
