Two identical cars collide head on. Each car is traveling at 100 km/h. The impact force on each car is the same as hitting a solid wall at:
(a) 100 km/h
(b) 200 km/h
(c) 150 km/h
(d) 50 km/h

hey mate...
here is your answer...
100 km/h, this is because Newton’s third law of motion, which states that for every action there is an equal and opposite reaction. Such that, when striking a sitting vehicle at 100 km/h, 100% of the force will be reflected at myself. Thus, each car is doing 100 km/h worth of force to itself and the opposite car, totalling to 200 km/h force.
Important to recognize these two cars driving toward each other were closing the gap at 200 km/h. And the concise answer is
Q: “The impact force on each car is the same as hitting a solid wall at what speed?”
A: 100 km/h, on each car.
This is assuming they do not have any sideways displacement, and that the cars crush the same exact ways, which I believe the question was phrased to reduce these variables.
hope it helps...
