Most persons are of the belief that the old time hard or solid iron cars are much safer in collisions than the new model softer cars. But how can newer, softer cars be safer in a collision, considering momentum?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
