WebJul 22, 2015 · Often, angular speeds of objects are given in terms of the number of revolutions per minute (rpm). To do calculations, sometimes it is necessary to convert this to value in radians per second. To do this, we use the fact that one revolution is equal to 360 o. Frequency is the total number of revolutions per unit time. It is defined, WebThe formula v = ωr can be rearranged to solve for the angular speed ω: This is also the angular speed at the outer edge of the wheel, where the radius is r = 0.220 m. The formula v = ωr can be used again to solve for the linear speed at that radius: v = ωr v = (100 rad/s) (0.220 m) ∴v = 22.0 m/s
