Question

A car is traveling at 10.0 m/s, and the driver sees a traffic light turn red. After 0.530 s (the reaction time), the driver applies the brakes, and the car decelerates at 6.00 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

Use v^2 =u^2 +2as
v =0, u =10, a = -6, s=?
S = 100/12 = 8.33m
