A body of mass 0.2 kg is suspended from a spring of force constant 80 Nm^-1. A damping force is acting on the system for which γ = 4 Nsm^-1. Write down the equation of motion of the system and calculate the period of its oscillations. Now a harmonic force F =10cos10t is applied. Calculate a and θ when the steady state response is given by a cos(ωt − θ).
