Problem Statement:
An ideal mass m sliding on a frictionless surface, attached via an ideal spring k to a rigid wall. The spring is at rest when the mass is centered at x=0. Find the equation of motion that the spring mass follows.
Solution:
We first begin by setting up a few equations from Newton's laws.
By Newton's first law:
'F=m'a \Rightarrow f_m(t)=m*\ddot{x}
