To test the performance of its tires, a car
travels along a perfectly flat (no banking) circular track of radius 151 m. The car increases
its speed at uniform rate of
at ≡
d |v|
dt = 2.51 m/s

until the tires start to skid.
If the tires start to skid when the car reaches
a speed of 25.9 m/s, what is the coefficient of
static friction between the tires and the road? The acceleration of gravity is 9.8 m/s
