Solve the all parts of given question:

Question: A driver in a moving car applies the brakes. The car slows to a final speed of 2.60 m/s over a distance of 40.0 m and a time interval of 8.45 s. The acceleration while braking is approximately constant.

Part A: What is the car's original speed before braking?

Part B: What is its acceleration during this time? (The car's initial velocity is in the positive direction. Indicate the direction with the sign of your answer.)
