A spring of negligible weight which stretches 1 inch under tension of 2 lb is fixed at one end and is attached to a weight of w lb at the other. It is found that resonance occur. when an axial periodic force 2 cos 2t lb acts on the weight. Show that when the free vibration have died out, the forced vibrations are given by x = ct sin 2t, and find the values of w and c.
