Skid friction

Find the smallest coefficient of skid friction between the car tires and the road so that the car can drive at a 200 m radius at 108 km/h and does not skid.

Correct answer:

k =  2.18

Step-by-step explanation:

r=200 m v=108 km/h m/s=108:3.6  m/s=30 m/s g=9.81 m/s2  Fg=mg Fo=mv2/r  Fok=Fg mv2/rk=mg  k=g r/v2=9.81 200/302=2.18
