s=50m
V=0m/s
V=V₀-at
S=V₀t - at²/2
at=V₀-at
t=V₀-V/a
s=V₀(V/a) - a(V₀/a)²/2
s=V₀²/a - V₀²/2a
s=2V₀²/a - V₀²/2a
s=V₀²/a
2as=V₀²
a= V₀²/2s
a=F/m=T/m=f*Fn/m=mg*f/m
a=fg
fg=V₀²/2s
f=V₀²/2sg
podstawiamy do wzoru
f=(10m/s)²/2*50m*10m/s²
f=100m²/s²/1000m²/s²
f=0,1
daj naj ;d
i cosik mało punkcików jak za takie duże zadanie ;<
