1.diketahui : lb=5cm Lk:80cm Fk:7,5n Dit : fb dan km 2. diketahui bidang miring : fb :1880n , L:5m ,h:1m Dit : f dan km ? Tolong pake caranya pleaseee

1. (Langsung rumus aja)
F = F × Lk = FK × Lb
7,5 × 0.8 = FK × 0.05
6 = FK × 0.05
FK = 6 / 0.05 = 120
FK = 120 N
KM = FB / FK = Lk / lb = 0.8 / 0.05 = 16 N

2. Dik = W = 1880 N
h = 1 m
s = 5 m
Dit = W? KM?
W = W × h = F × s
1880 × 1 = F × 5
1880 = F5
F = 1880 / 5 = 376 N
F = 376 N
KM = W / F = s / h = 5 / 1 = 5
KM = 5 N

Semoga Membantu!
Maaf kalau ada salah silahkan di Ralat :D
Cheerio!
