To test the performance of its tires, a car
travels along a perfectly flat (no banking) cir-
cular track of radius 516 m. the car increases
its speed at uniform rate of
at ≡
d |v|
dt = 3.89 m/s
2
until the tires start to skid.
if the tires start to skid when the car reaches
a speed of 32.8 m/s, what is the coefficient of
static friction between the tires and the road?
