Homework Statement
A perfectly elastic spring is attached to the ceiling and a mass m is hanging from the spring. he mass is in equilibrium when the spring is stretched a distance x(o). The mass is carefully lifted and held at rest in the position where the string is nether stretched nor compressed at all. The mass is then allowed to drop from rest. What is the maximum extension of the spring from its unstretched length?
Homework Equations
1/2 kx^2 perhaps...
The Attempt at a Solution
I know that the spring stretches more than x(o)... but cannot quite get myself together to prove it. 0.5kx^2=mgX, but that's by the time the spring stopped oscillating.. what's the length at 'MAX'imum? help me guys
