A mass on a spring undergoes SHM. When the mass is at its maximum distance from the equilibrium position, which of the following statements about it are true? (There could be more
Than one correct choice.)
A) Its speed is zero.
B) Its total mechanical energy is zero.
C) Its acceleration is zero.
D) Its elastic potential energy is zero.
E) Its kinetic energy is a maximum.

At the maximum distance from the equilibrium position, the mass is momentarily at rest, meaning its speed is zero. This is a characteristic of simple harmonic motion (SHM) where the velocity is zero at the maximum displacement due to all the energy being stored as potential energy at this point.
