How much energy is stored in a spring (k = 300 N/m) when it is compressed by 0.05 m from its rest position

C. 0.D. 60,E.E = 1/2 (300) (.......
A. 6.0 J
B. 1.5 J
C. 0.375 J
D. 60,000 J
E. 15 J

-
E = 1/2kx^2
E = 1/2 (300) (.05)^2

E = .375 J

C is the answer

-
you have to integrate 300x from 0 to 0.05. You get C as the answer.
