A car travels with an initial velocity, V, on a flat, level
road. The wheels of the car
suddenly lock. The wheels slide without rotating. The coefficient
of kinetic friction
between the wheels and the road is ux and the force of friction
stops the car after
the car slides a distance d. If this experiment was repeated on a
surface where
the coefficient of kinetic friction was reduced to uw/2, how far
would the car slide
before it stopped?
a. 4d
b. 2d
c. d
d. d/2
e. d/4
