Which would produce more force: driving into a very massive concrete wall with no "give," or having a head-on collision at the same speed with an identical car moving toward you with the same speed?

Question

Quizplus · Accepted Answer

The force produced in each scenario is determined by the change in momentum, which is the product of mass and velocity. In both scenarios, the mass and velocity of the object colliding is the same. Therefore, the force produced would be the same in both situations. It doesn't matter if the object collides with a concrete wall or another identical object.
