Dik : k₁ = k₂ = 1000 N/m disusun paralel k = k₁ + k₂ = 1000 + 1000 = 2000 N/m g = 10 m/s² m = 5 kg --- W = mg = 5.10 = 50 N Dit : Ep = ....? Jwb : W = k Δx Δx = W/k Ep = 1/2.W.Δx = 1/2.W²/k = 0,5 x 50²/2000 = 1250/200 = 0,625 J
disusun paralel
k = k₁ + k₂ = 1000 + 1000 = 2000 N/m
g = 10 m/s²
m = 5 kg --- W = mg = 5.10 = 50 N
Dit : Ep = ....?
Jwb : W = k Δx
Δx = W/k
Ep = 1/2.W.Δx
= 1/2.W²/k
= 0,5 x 50²/2000
= 1250/200
= 0,625 J
