I'm driving my car of mass 1000 kg at 100 km/hr when I accidentally hit the rear end of a truck of mass 5000 kg traveling in the same direction at 90 km/hr. My car and the truck lock together and move as a single object. Let F1 be the force the truck exerts on my car and let F2 be the force my car exerts on the truck. What is F1/F2 during the collision?
