Consider the forced spring-mass system: d^2x/dt^2 + ω^2 x = A sin (ωt) (3)

where in general ω ̸= ω0.

(a) Find the general solution to equation (3).

(b) Find the solution appropriate for the initial conditions x(0) = 0 and dx dt (0) = 0. (c) Let’s explore what happens as resonance is approached: Let ω = ω0 (1 + ϵ), where ϵ ≪ 1.

Expand your solution in (b) using the idea of a Taylor series about ω0 (you just need to keep the first two terms in such a series). In this way, find the form of the solution at resonance.

Newton’s law of cooling states that dx/dt = −k(x − A) where x is the temperature, t is time, A is the ambient temperature, and k > 0 is a constant. Suppose that A = A0cos(ωt) for some constants A0 and ω. That is, the ambient temperature oscillates (for example night and day temperatures). a) Find the general solution. b) In the long term, will the initial conditions make much of a difference?

A oscillating wave-energy-converter (WEC) can be modelled as a mass-spring system forced by sinusoidal waves. A simple model would be given by the following DE: x''(t) + x'(t) + Kx(t) = h sin(ωt), where x measures the position of the WEC; K is a tuning parameter, chosen so that the WEC resonates with the waves; h is the height of the waves; and ω is the frequency of the waves. (a) Find a particular solution for the model. (b) Using...
