Question

Assume the brakes in your car create a constant acceleration of 4.2 m/s2 regardless of your speed. How long does it take to stop if you are initially traveling 50 km/h? What distance do you go while stopping? Repeat the calculations for an initial speed of 100 km/h. What do you notice about the stopping times and distances?
