Consider the motorcyclist driving along a vertical circular track. Assume that the wheels of the motorcycle roll without slipping. Draw a free body diagram of the motoreyclist at the circled position. Draw a square around the force components that contribute to the centripetal acceleration. Draw a circle around the force components that contribute to the tangential acceleration. a. b. For each force component in your free body diagram in part (a), determine whether the work done by the force component is positive, negative, or zero.
