Aroadway is built with the following conditions: with ice on the road, when the coefficient of static friction between the road and rubber is 0.09, a car at rest must not slide into the ditch and a car traveling less than 50 km/h must not skid to the outside of the curve. the acceleration of gravity is 9.81 m/s.
what is the minimum radius of curvature of the curve?

Hello there.

A roadway is built with the following conditions: With ice on the road, when the coefficient of static friction between the road and rubber is 0.09, a carat rest must not slide into the ditch and a car traveling less than 50 km/h must not skid to the outside of the curve. The acceleration of gravity is 9.81 m/s.
What is the minimum radius of curvature of the curve?

5.09

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move.
