How do i go about this question?
Suppose a car is traveling at 20.0m/s, and the driver sees a traffic light turn red, After 0.530s has elapsed (the reaction time), the driver applies the brakes, and the car accelerates at 7.00m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
This is physics beyond belief. The car accelerated, not deaccelerated according to the problem statement. How could it stop?
Now if you meant the acceleration was -7m/s^2, as in brakes applied, solve for ...
solve for distance, then add the reaction distance, vo*.530
yea sorry that is what i meant ---> i should have wrote deceleration
