A car rounds a flat circular track with radius 682 m. The coefficient of static friction between the tires and track is 0.462. What is the maximum speed for the car if it's to stay on the track?

Question

please do you know the mass of your car?

michele_laino · Answer

sorry, it is not necessary

michele_laino · Answer

please on your car are acting two forces, one is the centrifugal force, whose direction is like radius of track towards the outside of that track, The second one, is the friction force, whose direction is like the radius of the track, towards the center of the track. Now, the equilibrum condition occurs, when those two forces have equal modulus.

please write the modulus of the centrifugal force and of the friction force
