Cars used to be built as ri34sx q) urlio hz:8ez,2m)8 xyypw 4whgid as possible to withstand czf;dn 5dvji 8v*wuo,6ollisions. Today, thoug wvn; do6,5fu ji*dv8zh, cars are designed to have “crumple zones” 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.
