The θ integration fails if α is non-constant. There is also a type of situation where the step before the integration fails, involving ω.
Question 3: derive θ = θ0 + (ω + ω0) t/2.
You probably need to use prior derived results.
Our unforced spring mass model is mx00 + βx0 + kx = 0 with m, β, k >0. We know physically that our spring will eventually come to rest nomatter the initial conditions or the values of m, β, or k. If our modelis a good model, all solutions x(t) should approach 0 as t → ∞. Foreach of the three cases below, explain how we know that both rootsr1,2 =−β ± Sqrt(β^2 − 4km)/2mwill lead to solutions that exhibit exponentialdecay.(a) β^2 − 4km > 0.
(b) β^2 − 4km =0.
(c) β^2 − 4km >= 0.
Consider the solution tothe harmonic oscillator given above by x(t)=Ccos(wt−v)
Prove tha
tx(t0)=x(t0+2piw)
In other words, the solution has the same value at time:t0 and at time:t0+2piw
regardless of what value we have for ?0. The value 2piw is then the period T of the harmonic oscillator.
