A car at the Indianapolis 500 accelerates uniformly from the pit area, going from rest to 260 km/h in a semicircular arc with a radius of 230 m .   a.) Determine the tangential and radial acceleration of the car when it is halfway through the arc, assuming constant tangential acceleration. b.) If the curve were flat, what would the coefficient of static friction would be necessary between the tires and the road to provide this acceleration with no slipping or skidding?

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.
