In figure, the stiffness of the spring is `k` and mass of the block is `m`. The pulley is fixed. Initially, the block `m` is held such that the elongation in the spring is zero and then released from rest. Find:
a. the maximum elongation in the spring.
b. the maximum speed of the block `m`. Neglect the mass of the spring and that of the string. Also neglect the friction.
