pliss tolong di jawab yah teman teman bsk di kumpul. Lumayan poinnya banyakloh

PESAWAT SEDERHANA
• bidang miring

h = 2,5 m
S = 15 m
w = 1200 N
KM = __?
F = __?

a][ keuntungan mekanik
KM = S / h
KM = 15 / 2,5
KM = 6 ← jwb

b][ kuasa
F = w / KM
F = 1200 / 6
F = 200 N ← jwb

atau
F • S= w • h
F = w • (h / S)
F = 1200 • (2,5 / 15)
F = 1200 • (1/6)
F = 200 N ←
