(a) what minimum speed must he have at the top of thecircle if the tires of the motorcycle are not to lose contact withthe sphere?
m/s
(b) at the bottom of the circle, his speed is twice the valuecalculated in part (a). what is the magnitude of the normal forceexerted on the motorcycle by the sphere at this point?
