To test the performance of its tires, a car
travels along a perfectly flat (no banking) cir-
cular track of radius 564 m. the car increases
its speed at uniform rate of
a 101
al = 410 = 3.62 m/s2
dt
until the tires start to skid.
if the tires start to skid when the car reaches
a speed of 35 m/s, what is the coefficient of
static frictionsbetween the tires and the road?
