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...
