Mark the position of each of the labeled points at a later time when the wheel has completed one half of a turn. Sketch a velocity vector at each point. For each labeled point, how does the velocity compare to the velocity at the earlier time in part A? Discuss both on magnitude and direction. lect whgns sd lo Top view Wheel spins counterclockwise Is there one single linear velocity vector that applies to every point on the wheel at all times? Explain.
