Oblicz jaką pracę wykona Ania podnosząc ruchem jednostajnym pudełko o masie 3 kg na wysokość 75cm. Daje Naj C:
W=F *s
F=Fg
Fg=m* g
m=3 kg
g=10 m/s^2
s=75 cm=0,75 m
Fg=3 *10=30 N
W=30N *0,75 m=22,5 J
m = 3 kgs = 75 cm = 0,75 mW = F * sF = m * gg = 10 m/s2F = 3 kg * 10 m/s2 = 30 NW = 3O N * 0,75 m = 22,5 J
