Homework Statement
Since the total energy in a spring is
(1/2)kA^2
Can we rearrange this...
given k=F/x
(1/2)(FA^2/x)
Since x is also the amplitude, we have:
(1/2)(FA)
(1/2)(mgA)
I am pretty sure this is wrong, but why?
Thanks
yes, where F is the max force in the spring and A is the absolute value of x.Homework Statement
