17.1.5—Graphical representations of the variations of displacement, velocity and question 1
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.
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.

State:
one time at which the mass is moving with maximum speed
