An exercise spring has a spring constant of 315 N/m. How much work is required to stretch the spring 30 cm? What force is needed to stretch the spring 30 cm?

  • Physical Science -

    Use meters for the displacement, X.

    Force = k*X = 315*0.3 = 94.5 N
    Work = (1/2)*k*X^2 = (1/2)(315)(.3)^2
    = 14.2 J
