Sebuah pegas memiliki konstanta 400n/m.pegas diberi beban bermassa 10 kg ternyata panjang pegas menjadi 85 cm.berapa panjang pegas mula mula?g = 10 m/sekon kuadrat

F = k. Δx --> Δx = x akhir - x awal = 85 - x awal m.g = k. Δx 10.10 = 400. Δx 100 = 400.Δx
Δx = 1/4 m = 1/4 . 100 cm = 25 cm
Δx = 85 - x awal x awal = 85 - Δx = 85 - 25 = 60 cm

whongaliem F = k .Δx m.g = k . Δx 10 . 10 = 400 . Δx 100 = 400 . Δx Δx = Δx = 0,25 m Δx = 25 cm Lo = Lt - Δx = 85 cm - 25 cm = 60 cm
= 85 - x awal
m.g = k. Δx
10.10 = 400. Δx
100 = 400.Δx
Δx = 1/4 m
= 1/4 . 100 cm
= 25 cm
Δx = 85 - x awal
x awal = 85 - Δx
= 85 - 25
= 60 cm
m.g = k . Δx
10 . 10 = 400 . Δx
100 = 400 . Δx
Δx =
Δx = 0,25 m
Δx = 25 cm
Lo = Lt - Δx
= 85 cm - 25 cm
= 60 cm
