Question:
Solve Prob. 12.14, assuming that the brakes of car B fail to operate. Problem 12.14: A light train made up of two cars is traveling at 55 mi/h when the brakes are applied to both cars. Knowing that car A has a weight of 55,000 lb and car B has a weight of 44,000 lb and that the braking force is 7000 lb on each car, determine
(a) The distance traveled by the train before it comes to a stop,
(b) The force in the coupling between the cars while the train is slowingdown.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
