Homework Statement
A block is hung from a vertical spring. The spring stretches (h = .0650 m ) for a particular instant in time. Consider the earth, spring, and block to be in the system. If m = .865 kg and k = 125 N/m, find the change in the systems potential energy between the two times depicted.
Homework Equations
(1/2)ky^2(final) - (1/2)ky^2(initial)
The Attempt at a Solution
My book actually doesn't have an answer for this question. I assume the equation I wrote above is the one I use.
Plugging in I got:
(1/2)(125)(-.0650)^2 - (1/2)(125)(0) = .2640625
does the answer I got seem correct to everybody?
