Tolong bantuannya ya.... Pake rumus nya ya ?

Diketahui : F = 0,5 x 10 = 5 N
h = 2m
F = 1/2 w
W = 2.F = 2.5 = 10 N

Jawab :
KM = w/F
= 10/5 = 2

s/h = KM
s/2 = 2
s = 2.2 = 4,0 m (a)

Maaf kalau salah dan semoga bisa membantu :)

F = 0,5 N
W = 1 N
h = 2 m
s = ?
W.h = F.s
1.2 = 0,5.s
2 = 0,5.s
2/0,5 = s
4,0 = s
panjang papan yg dibutuhkan (s) = 4,0 m (A)
-maaf kalo salah-
