I have this question on my homework, but I think maybe all the answers are wrong. I figure it should be C since the road is icy, but shouldn't I be using the coefficient of static friction instead of kinetic? any help is appreciated. thanks.
As a car skids with its wheels locked trying to stop on a road
covered with ice and snow,
the force of friction between the icy road and the tires will
usually be: (Please note that
"normal" and "perpendicular" have the same meaning)
a. greater than the normal force of the road times the coefficient
of static friction
b. equal to the normal force of the road times the coefficient of
static friction
c. less than the normal force of the road times the coefficient of
kinetic friction
d. greater than the normal force of the road times the coefficient
of kinetic friction
e. equal to the normal force of the road times the coefficient of
kinetic friction.
