Question:
To stop a car, first you require a certain reaction time to begin braking; then the car slows at a constant rate. Suppose that the total distance moved by your car during these two phases is 56.7 m when its initial speed is 80.5 km/h, and 24.4 m when its initial speed is 483 km/h. What are?
(a) Your reaction time and
(b) The magnitude of the acceleration?
