A 1900 kg car moves along a horizontal road
at speed v0 = 26.4 m/s. The road is wet, so
the static friction coefficient between the tires
and the road is only μs = 0.17 and the kinetic
friction coefficient is even lower, μk = 0.119.
The acceleration of gravity is 9.8 m/s2 .
What is the shortest possible stopping dis-
tance for the car under such conditions? Use
g = 9.8 m/s2 and neglect the reaction time of
the driver.
