F =10 N
Δx =4 cm = 0,04 m
Dit. Ep................?
penyelesaian :
cari k:
k = F/Δx
=10/0,04
=250 N/m
maka,
Ep =1/2.k.x²
=1/2.250.(0,04)²
=125.0,0016
=0,2 J
Δx = 4 cm = 0,04 m
F = 10 N
Ditanyakan : Ep ?
Dijawab :
k = F/Δx
= 10/0,04
= 250 N/m
Energi Potensial :
Ep = 1/2 k Δx²
= 1/2 x 250 x 0,04²
= 1/2 x 250 x 0,0016
= 0,2 J
