Compute all parts of given question:
Question: A car is moving with a speed of 27 m/s down a long, straight road. When it is 130 m from a traffic light, the light turns red.
Part A: With what constant acceleration must the car move in order to stop at the light?
Part B: How long does it take the car to stop?
Please show me how you solve the question.
