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

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
