Problem 6. The simple harmonic motion of a 2 kg mass attached to a spring with spring constant, k = 32, is governed by the differential equation. dy 2- + 32y(t) = 0 which has general solution dt2 y(t) = c1 cos(4t) +c2 sin(4t). • Show that y(t) = 5 cos(4t +) is a solution to this differential equation by expressing this function as a linear combination of y1(t) = cos(4t) and y2(t) = sin(4t). • Identify the amplitude, frequency and phase for this simple harmonic motion and sketch a graph of y(t).
