Witam,
Tor kolejowy ma kształt okręgu o promieniu r=15km. Na przeciwległych krańcach średnicy tego toru, czyli odległości 2r znajdują się dwa pociągi jadące z prędkościami v₁ i v₂ jak na rysunku.
a) Po jakim czasie pociągi spotkają się jeżeli ich prędkości mają wartości v₁=68km/h i v₂=53km/h.
b) Gdyby pociągi znajdowały się na osobnych równoległych torach mogłyby mijać się wielokrotnie. Jaka byłaby odległość między tymi pociągami zarówno wzdłuż toru jak i wzdłuż lini prostej po czasie 18h 50min 24s ?
