Question

Physics: A car....?

A car is traveling at 14.0 m/s, and the driver sees a traffic light turn red. After 0.560 s (the reaction time), the driver applies the brakes, and the car decelerates at 9.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first sees the red light?

Answer 1

I got `18.73m`

Answer 2

`"Another solution way ..."`

Explanation:

• the velocity-time graph of the car has been given below.
• The area below velocity-time graph is equal to displacement of the car.
• The car is moving at constant velocity of 14 m/s between the points A and B.
• The velocity of the car decreases between the points B and C.
• The sum of the green and red areas is answer to your problem..
