Răspuns :
trebuie de aflat timpull in care a cazut aceasta astfel:
t=1080m:6m/sec.=180sec. sau 3 minute
t=1080m:6m/sec.=180sec. sau 3 minute
[tex]v=6 \ m/s \\ h=d=1 \ 080 \ m \\ \boxed{t-?} \\ \bold{Rezolvare:} \\ \boxed{v=\frac{d}{t}} \\ t=\frac{d}{v} \\ t=\frac{1 \ 080 \ m}{6 \ m/s} \\ \Rightarrow \boxed{t=180 \ s=\bold{3 \ min}}[/tex]
