To test the performance of its tires, a car
travels along a perfectly flat (no banking) cir-
cular track of radius 284 m. The car increases
its speed at uniform rate of
at
4.8 m/s?
dt
until the tires start to skid.
If the tires start to skid when the car reaches
a speed of 39.6 m/s, what is the coefficient of
static friction between the tires and the road?
