A car has a mass of 1520kg. While traveling at 20 m/s, the driver applies the brakes to stop the car on a wet surface with a 0.40 coefficient of friction.
A) How far does the car travel before stopping?
B) If a different car with a mass of 1.5 times greater is on the road traveling a the same speed and the coefficient of friction between the road and the tires is the same, what will its stopping distance be? Explain your results.
