Homework Equations
Fs = -kx
w = mg
The Attempt at a Solution
I said that when the spring is stretched out at its max, the weight pulling down will equal the force of the spring pulling up.
Fs=w
-kx = mg
-(1500)(x) = (3)(-9.81)
x = 0.01962 m
The solution key tells me the max stretch is double this amount, 0.039 m. What is wrong with my approach?
