Homework Statement
A spring is hung vertically from a support. A mass of 4.5 kg is hung from the lower end of the spring and is slowly lowered a distance of 22.0 cm until equilibrium is reached. This mass is then lowered to a point 15.0 cm below the equilibrium point and is then released, after with the mass vibrates up and down in simple harmonic motion.
It says the answer is 200n/m but I must be doing something wrong!
Homework Equations
k=f/x
f=-kx
The Attempt at a Solution
x=-.15 m
f= 4.5 * 9.8=44.1N
k=f/x, k=44.1/-.15= -294?
what am I doing wrong??
