Asked by Kyle
Suppose that a NASCAR race car is moving to the right with a constant velocity of +92 m/s. What is the average acceleration of the car? (b) Twelve seconds later, the car is halfway around the track and traveling in the opposite direction with the same speed. What is the average acceleration of the car?

constant velocity means zero acceleration.
average acceleration= 2*92/12 m/s^2 in the direction to the left.
average acceleration= 2*92/12 m/s^2 in the direction to the left.
