Awheel of radius b rolls along the ground with constant forward acceleration a0. show that, at any given instant, the magnitude of the acceleration of any point on the wheel is + v4/b2)112 relative to the center of the wheel and is also a0[2 + 2 coso + — (2v2/a0b)sin 01112 relative to the ground. here v is the instantaneous forward speed, and 0 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?
