Question

Tolong jawabkan... caranya juga ya..

Answer 1

S = 40 m
F1 = 200 N
W = 14 kJ = 14.000 J
Penyelesaian:
W = (F1+F2)(s)
14.000 = (200+F2)(40)
200+F2 = 14000/40
200+F2 = 350
F2 = 350-200
F2 = 150 N (B)

Answer 2

Mis:Ivan=I Ryan=R
dik:s=40m
F Ivan=200N
W=14kj=14.000J
dit:F Ryan...?
peny:W=F×S
14.000=(F Ryan+F Ivan) ×S
14.000=(F Ryan+200)×40
14.000=40F ryan +8000
-40F ryan=8000-14000
-40F ryan=-6000
40F ryan=6000
F ryan=6000:40
F ryan=150N
