Diketahui :
h = 6 m
a = 8 m
F = 50 N
Ditanyakan : KM dan W ?
Dijawab ;
s² = h² + a²
= 6² + 8²
= 36 + 64
s = √100
s = 10 m
Jadi KM = s/h = 10/6 = 1,67
Berat :
F = h/s x W
W = (Fxs) / h
= (50x10)/6
= 83,3 N
jawaban B
Nomor 8 :
Diketahui :
A1 = 10 m2
A2 = 40 m2
W = 2000 N
Ditanyakan ; F ?
Dijawab :
F/W = A1/A2
F/2000 = 10/40
F/2000 = 1/4
F = 2000/4
F = 500 N
