| Agnus has a good reason to be distracted, I suppose, but she had better be careful. She is going around the curve at 20 m/s and the tires are just at the point of skidding on the highway!
Since you know that the mass of the car is 2000 kg and the radius of the curve is 50 m, you can calculate the centripetal force acting on the car. Since this force results from friction, you now have all the necessary information to calculate the coefficient of static friction between the tires and the road surface. Aren't you lucky? Do it! |
