You and your family take a road trip on a long holiday weekend. In a certain section of the trip where the road is particularly uneven, the car goes over a bump that is curved downward with a radius of 16.0 m. See diagram below. mass of the car and its passengers is 1200 kg. (a) When the car is at the highest point of the bump its speed is 7.05 m/s. Determine the magnitude and direction of the force exerted by the road on the car at this highest point. magnitude direction Select v (b) If the speed at the highest point is above a certain maximum value the car will lose contact with the road. Calculate this maximum speed. m/s

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.
