What is the angular speel of a 19-in. diameter bicycle wheel if the bicycle if traveling at 29 ft/s?

  • trigonometry -

    Speed = R w
    R = 9.5 inch
    Speed = 29*12 = 348 inch/s
    w = angular speed = 348/9.5 = ? radians/s

    Speed and R must both use the same length units when calculating w. I chose to use inches
