Cars used to be built x1v.1; bxgv2 d)udbnj sp2fzd,q27 b3wp6l (nb la8euas rigid as possible to withstand collisions. Today, though, cars are designed to have “crumple zones” that collapse upon impact. What is the advantage of this nepdas 2 p7b,n3q 82 wlf(ez6ulbw design?
参考答案: “Crumple zones” are similar to air bags in that
they increase the time of interaction during a collision, and therefore lower
the average force required for the change in momentum that the car undergoes in
the collision.
