Find what is the minimum safe distance

Reference no: EM13523901

You are driving just behind a second car and both of you are moving at a speed 68 . If the car in front of you suddenly slams on her brakes, you will apply your breaks as quickly as you can. This time is called your reaction time and is typically 200 ms. Assume both cars accelerate at the same rate of - 7.00 .

What is the initial speed of the two cars in m/s?

What is the closest distance your front bumper can be behind the rear bumper of the car in front of you and not crash into her car?

If you are very tired after a long night, or you are texting, or you are alcohol impaired, your reaction time can be twice your standard reaction time. What is the minimum safe distance now?
