A car is traveling at 56.0 km/h on a flat highway. If the coefficient of friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop?

2. Relevant equations

μ=-a/g

v^{2}=vo^{2}+ 2 a x

3. The attempt at a solution

56.0 km/h = 15.6 m/s

0.100=-a / 9.8 m/s^{2}

a= 0.98 m/s^{2}

0=(15.6 m/s)^{2}+ 2 (0.98m/s^{2}) x

x= 245.3 m
