Cars used to be built as tksh,wp*qx q wb w30h3z(vou(2* qf1krigid as possible to withstand collisions vhxat54x x .7s;ad /ijcygju6)2u6uf. Today, though, cars are designed to have “crumple zones” 7j/2 ct vxx;u5j y6hi ud.g6a)s4aufx that collapse upon impact. What is the advantage of this new 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.
