Period 2Question 1

Consider a point P on a bicycle wheel that is momentarily in contact with the ground as the bicycle rolls to the right without sliding across the ground with constant speed. At that moment:

1. The acceleration of P is downward2. The velocity of P points leftward 3. The acceleration of P is zero4. The velocity of P points to the right5. The speed of P with respect to the

ground is zero
