Solve the following questions:
Question I: Suppose that a NASCAR race car is moving to the right with a constant velocity of + 98 m/s. What is the average acceleration of the car?
Question II: 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?
Please show all work so I can fully understand all concepts! Thanks.
