You are the technical consultant for a car-chase sequence in an action movie. In a certain part of the scene, the director wants a car to round a certain curve while braking from 66 miles per hour to rest before it travels 290 feet along the curve. You measure the radius of the curve to be 590 feet. Is this scene possible? Defend your response and suggest an alternative scene if it is not possible. Answer: Reduce speed to 22 meters per second or use a concrete road.

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.
