1. Period 2 Question 1

2. 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
