Height

In summary: Look at post #6. When you say "you need to know the height when using the ever easy equation of potential energy equals mass times gravity times height.", flyingpig might think he needs to know the value of d or h. And he doesn't need these...In summary, a 5kg mass hung vertically on a light spring stretches the spring by 3 cm. An external agent must do work to stretch the spring by 4 cm from its equilibrium position. The spring is hung vertically from the ceiling. The acceleration due to gravity is treated as a constant 9.81 m/s2. The work can be calculated by finding the potential energy stored in the spring, which can be determined by knowing the value of k through the

Oh lol

mg = kx

mg/x = (5*10)(3) = 50/3 = 16.7N/m

16.7N/m * -3.5 * 10^-4 + 50 * 1 * 10^-2 = 0.49J Still positive?
