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 downward 2. The velocity of P points leftward  3. The acceleration of P is zero 4. The velocity of P  points to the right 5. The speed of P with respect to the ground is  zero
