Solve the both part of given question:
Question: To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 53.2 m when its initial speed is 75.9 km/h, and 24.3 m when its initial speed is 47.4 km/h.
Part A: What is your reaction time?
Part B: What is the magnitude of the deceleration?
