How much energy is stored in a spring with a spring constant of 250 N/m if the spring is compressed a distance of 0.46 m from its free length?


Group of answer choices

120 J

58 J

53 J

26 J

14000 J

Respuesta :

F=-ks

(F=Force) (k=spring constant) (s=displacement)

F=-(250)(0.46)
F=-115N

W=Fs
W=115(0.46)
W=52.9J

W= ∆Energy
So ∆E=52.9 J

Answer: 53J (third option)
