Question

Mohon Bantuannya mau dikumpul 3 jam lagi...

Answer 1

pegas 1
Kp = 2K 

1/ K total = 1/2K + 1/K + 1/K
               = (1 + 2 + 2) / 2K
K total = 2K / 5

Pegas 2
Kp = 3K
1/K total = 1/3K + 1/K
              = (1 + 3 ) 3K
K total    = 3K / 4

pertambahan panjang
x₁ / x₂ = K₂ / K₁
           = (3K / 4) / (2K / 5)
           = 15 / 8

jadi x₁ : x₂ = 15 : 8
Jawaban : E
