A body of mass \( m \) is attached by an inelastic string to a suspended spring of spring constant \( k \). Both the string and the spring have negligible mass and the string is inextensible and of length \( L \). Initially, the mass \( m \) is at rest.

If the mass \( m \), from the initial position of rest, is pulled down a distance \( A \) and then released, assuming that the string remains taut throughout the motion, the maximum (downward) acceleration of the oscillating body will be
(1) \( \frac{k A}{m} \)
(2) \( \frac{k A}{2 m} \)
(3) \( \frac{g}{2} \)
(4) \( g \)
