A roller coaster car loaded with passengers, has a mass of 500. kg; the radius of curvature of the track at the bottom point of a dip is 12.0 m. The vehicle has a speed of 18.0 m/s at this point. In the space below, draw a free-body diagram for the car (label forces according to type). Calculate the acceleration and the net force acting upon the car. PSYW Calculate the force exerted on the vehicle by the track? PSYW

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
