Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

A car drives around two circular curves on two different roads. The two curves have the same radius of curvature. And coincidentally, the maximum speed that the car can drive through either of the turns is the same for both roads. The first road is frictionless, but it is banked at 14.5 degrees from the horizontal. The other turn is flat. What is the coefficient of friction between the car tires and the road on the unbanked turn?
