You have been hired as an expert witness in a court caseinvolving an automobile accident. The accident involvedcar A of mass 1500 kg which crashed into stationary car Bof mass 1100 kg. The driver of car A applied his brakes15 m before he skidded and crashed into car B. After thecollision, car A slid 18 m while car B slid 30 m. The coefficient of kinetic friction between the locked wheels and the road was measured to be 0.60. Show that the driver of car A was exceeding the 55 mi/h (90km/h) speed limit before applying the brakes.

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?”
