The stopping distance d is the distance a vehicle will travel from the point when the
brakes are fully applied to when it comes to a
complete stop. A racecar with a combined
mass m of 25 kg with the driver is traveling
along a racetrack at a velocity v of 100 m/s.
The coefficient of friction u between wet
asphalt and rubber is 0.20, while the
coefficient between dry asphalt and rubber
can reach 0.90. Which of the following
statements is true about the stopping
distance assuming friction does all the work
for stopping the car?
