To stop a car, first you require a certain reaction timeto begin braking. Then the car slows down at a constant rate.Suppose that the total distance moved by your car during these twophases is 56.7 m when its initial speed is 76.5 km/h, and 24.4 mwhen the initial speed is 44.3 km/h.
A) What is your reaction time?
B) What is the magnitude of the deceleration?
