A bicycle wheel of radius R rolls to the right without slipping. The velocity of the axle of
the wheel relative to an observer standing on the road is i.
At the moment shown in the figure Point A is in contact with the road, and Point B is at
the top of the wheel.
R
A. At the moment shown what is the instantaneous velocity of Point A relative to an
observer standing on the road?
B. For the person riding on the bicycle, about what point is the wheel rotating? Why
is this point different than any other point on the wheel? What are the velocities
of Points A and B and the axel at the moment shown in the figure? What is the
angular velocity wB of the wheel?
C. For an observer standing on the road, about what point is the wheel rotating? For
this observer what is the angular velocity Wr of the wheel? What is the
instantaneous velocity of Point B for this observer at the moment shown in the
figure?
