A wheel of radius b rolls along tire ground with constant forward acceleration a0. Show that, at any given instant, the magnitude of the acceleration of any point on tire wheel is  relative to the center of the wheel and is also  relative to the ground. Here υ is the instantaneous forward speed, and θ defines the location of the point on the wheel, measured forward from the highest point. Which point has the greatest acceleration relative to the ground?
