3. When an oscillator with natural frequency wo is driven by another oscillator with a different natural frequency w, the phenomenon of beats can occur. The existence of beats is very useful when tuning a string instrument by ear. Show that the solution of the undamped oscillator IVP y', +Hy-Asin(wt), y(0)--, wo+w with y(0)-0, leads to beats, by first solving the IVP and then plotting the solution using MATLAB for A w = 1.1 and t є [0, 1001. 1,...

Problem 2. Recall that any undamped spring-mass system is described by an initial value problem of the form m" + ky= 0, (0) = 0, v(0) = to, where m is the mass and k is the spring constant. Since there is no damping, we would expect that no energy is lost as the mass moves. That is, the total energy (potential plus kinetic) in the system at any time I should equal the initial amount of energy in the...
