Cars used to be built as rigj/*)vimprhskv ;9b(jm; 8r8swz .rvpid as possible to withsto 2otj 9zj8pf6mb;8a :yhmo7oand collisions. Today, though, cars are designed to have “crumple zones” that collapse upon impact. What is the ad ;hz8oyjjmo 79m b po2:6a8otfvantage 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.
