Peter is driving at a constant velocity of 20 m/s. Suddenly, he sees an obstacle in the road. To stop the car, first he needs a certain time to react and begin braking. Then, the car slows down at constant rate, to a complete stop. Peter's reaction time is 0.50 s and the maximum deceleration of his car is 6.0 m/s. Calculate the total distance traveled (during these two phases). Kindly answer in full And make a model
