Vb=aA车t t=10S 即10秒后A车速度为10m/s 且距离最远 Smax=VB车t Smax=200m

Ehe ich aus freiem Willen und mit klaren Sinnen aus dem Leben scheide,drängt es mich,eine letzte Pflicht zu erfüllen:diesem wundervollen Lande Brasilien innig zu danken,dass es mir und meiner Arbeit so gut und gastlich Rast gegeben.Mit jedem Tage habe ich dies Land mehr lieben gelernt,und nirgends hätte ich mir mein Leben lieber vom Grunde aus neu aufgebaut,nachdem die Heimat meiner Sprache für mich untergegangen ist und meine geistige Heimat Europa sich selber vernichtet.Aber nach dem 60.Jahre bedürfte es besonderer Kräfte,um noch einmal völlig neu zu beginnen.Und die meinen sind durch die langen Jahre heimatlosen Wanderns erschöpft.（ （So halte ich es für besser,rechtzeitig und in aufrechter Haltung ein Leben abzuschließen,dem geistige Arbeit immer die lauterste Freude und persönliche Freiheit das höchste Gut dieser Erde gewesen.） ） Ich grüße alle meine Freunde!Mögen sie die Morgenröte noch sehen,nach der langen Nacht!Ich,allzu Ungeduldiger,gehe ihnen voraus.(Stefan Zweig in seinem Abschiedsbrief)

杜甫《春夜喜雨》
好雨知时节，当春乃发生。
随风潜入夜，润物细无声。
野径云俱黑，江船火独明。
晓看红湿处，花重锦官城。
译文　　春雨知道适应季节，当万物萌发生长时，它伴随着春风，在夜晚偷偷地及时降临，滋润万物又细微无声。郊野的小路和空中的云朵躲在黑暗之中，江上渔船的灯火却格外明亮。待到天明，看那细雨滋润的红花，映着曙光分外鲜艳，饱含雨露的花朵开满了锦官城。...
