S jakým zrychlením se pohybuje startující letadlo, jestliže při rozjezdu z klidu urazí rovnoměrně zrychleným pohybem za 10 s dráhu dlouhou 200 m?
Správná odpověď je: B
Pro rychlost rovnoměrně zrychleného pohybu bez počáteční rychlosti platí vzorec 
. Pro dráhu tohoto pohybu platí vzorec 
. V tomto případě lze zrychlení vyjádřit přímo ze vzorce pro dráhu, a sice:
a = (2 · s)/t2 = (2 · 200 m)/100 s2 = 400 m/100 s2 = 4 m · s−2.
