# Compound Harmonic Motion

**1. The problem statement, all variables and given/known data**

Determine the motion of this mechanical system satisfying the initial conditions :-

y1(0) = 1

y2(0) = 2

y1′(0) = -2*sqrt(6)

y2′(0) = sqrt(6)

Hint : there are 4 different methods you can use to solve this problem. They all give the same exact result.

I need to know what y1(t) and y2(t) are, please

**2. Relevant equations**

I know the shm equations- are they valid here?

**3. The attempt at a solution**

total k = 1/(1/k1+1/k2)

total m = m1 + m2

Help!
