The equation for motion for the ideal spring-mass system as derived in class is, ma+kx=0, where, m=mass, a=acceleration, k=spring stiffness, and x=displacement.
1) Describe briefly how the equation for motion arises from classical laws of mechanics.
2) What types of motion satisfy this equation? Why?
