A driver in a moving car applies the brakes. The car slows to a final speed of 1.45 m/s over a distance of 40.0 m and a time interval of 9.50 s. The acceleration while braking is approximately constant.
(a) What is the car's original speed before braking? (m/s)
(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.) (m/s^2)
