Cars used to be built as rigid as lfglq(+iex9 )possiw komdx,ait b fvl02d e./z/hup 276zs.c+i+eble to withstand collisions. Today, though, cars are designed to have “crumple zones” that collapse upe,ob x zdp.+ticid2zve20whal +mf6.//k s7uon 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.
