Given a mass, m-5 kg, attached to a spring with spring constant, k-20 N/m:
Assuming undamped system, setup the model and solve for the particular solution given initial conditions, y(0) - 15 y(π/4)= 10
y(t) = 10cos (t) +15sin(t)
Oy(t)=15cos(2t) + 10sin(2t)
y(t) = 15e (2) +10e(-2)
y(t) = 10e (2) + 15e(-2)
None
