A 2,500 kilogram vehicle initially moving eastward at fix speed 6m/s in a parking lot has it's steering wheel turned thus as to make the pavement keep exerting a 7,500 Newton horizontal force component on the car, rightward and perpendicular to the direction of motion.
(a) Sketch the path the car follows.
(b) Find how far will the car be from its initial position when it's moving westward?
