is the momentum and force the same for a equal mass cars when: 1. they collide head on both at 30 m/s. 2.one collides with a brick wall at 60m/s
In the second case, the force and momentum change of each moving car are higher, since the original momemtum of each moving car before collision is higher.
Moving cars are brought to rest in both cases.
