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

At the equilibrium position, the acceleration is zero because the net force is zero. The elastic potential energy is zero because the spring is neither compressed nor stretched. The kinetic energy is maximum because all the energy is converted from potential to kinetic at this point.
