Odpowiedź :
v=108 km/h=30m/s
a=3m/s
V=a*t
t=V/a
t=30/3=10s
s=(at²)/2
s=(3* 100)/2=150m
a=3m/s
V=a*t
t=V/a
t=30/3=10s
s=(at²)/2
s=(3* 100)/2=150m
108km/h = 30 m/s
Najpierw liczymy czas:
t = v/a
t = 30m/s/3 m/s²
t = 10s
Teraz drogę:
s = at²/2
s = 3 m/s² * 100s / 2
s = 150m
Najpierw liczymy czas:
t = v/a
t = 30m/s/3 m/s²
t = 10s
Teraz drogę:
s = at²/2
s = 3 m/s² * 100s / 2
s = 150m
