A spring is hung vertically from a fixed point. A mass M is hung from the other end of the spring, as illustrated in Fig. 3.1. L mass M spring Fig. 3.1 The mass is displaced downwards and then released. The subsequent motion of the mass is simple harmonic. The variation with time t of the length L of the spring is shown in Fig. 3.2. 1.0 0 0.2 0.4 0.6 0.8 t / s 8 10 12 14 16 L / cm Fig. 3.2
