Tolong dibantu no 1 2

1)•W.lw=F.lf
= W.lw/lf
=3000.1/4
=750N
KM= W/F
=3000/750
=4
• W.lw=F.lf
W=F.lf/lw
=1200N.300cm/40cm
=360000/40
=9000N
KM= W/F
=9000/1200
=7,5
• W.lw=F.lf
lf= W.lw/F
= 5600N.5/80N
= 28000/80
=350cm
KM = W/F
=5600/80
=70
(Maaf kayakny salah yg no ini soalny KM ny beda)
• W.lw= F.lf
lw= F.lf/W
= 10N.50/200N
=500/200
=2,5cm
KM= W/F
= 200/ 10
= 20

2) F1/A1=W/A2
W= F1.A2/A1
=40N. 12000/40
=12000N
Maaf ya klok salah,.
