Three cars of equal mass and velocities are traveling south down 41 through Acworth. When they each see the traffic light change from yellow to red, they step on the brake pedal. Car A comes to a stop in a distance of 200 meters while car B comes to a stop in 100 meters and Car C comes to a stop in 50 meters. Which car will have the greatest force exerted on it? Required to answer. Single choice.
