Mam podane dane do zadania i muszę obliczyć moc.
p=w/t
p=?
czas=5s
masa= 1000kg
V=108km/h
W=F*s
F= 1000*10= 10 000N
v=108km/h= 108000/3600=30m/s
s=30*5=150 m
W= 10 000*150=1500000J
p= 1500000/5=300000
Dane:
t=5 s
m=1000 kg
v=108 km/h
Szukane:
P=?
Wzór:
P=W/t
F=1000 kg*10 m/s2=10 000 N
v=108 km/h=30 m/s
s=30 m/s * 5 s=150 m
W=10 000 N * 150 m = 1500000J
P=1500000 J/5 s = 300000 W
Moc wynosi 300000 W.
