V= g * t = układ równań
h= 1/2v * t
h=10m
g=9,8m/s2
ile wynosi v?
v = gt
h = vt/2
wstawiamy v do drugiego równania
h = gtt/2 = gt²/2
wyznaczamy t
t = √2h/g
t = √2 x 10m/10m/s² = 1,41s
v = 10m/s² x 1,41s = 14,1m/s

(1) v = g·t
(2) h = ½v·t
Podstawiam (1) do (2), otrzymując:
h = ½g·t·t
h = ½gt² I*2
gt² = 2h /:g
t² = 2h/g
t = √(2h/g) = √(2·10m/9,8m/s²) = √2 s
t = 1,41
v = g·t = 9,8m/s²·1,41s = 13,8 m/s
v = 13,8 m/s
