In simple harmonic motion, when is the speed the greatest? (There could be more than one correct choice.)
A) when the magnitude of the acceleration is a maximum
B) when the potential energy is a zero
C) when the potential energy is a maximum
D) when the displacement is a maximum
E) when the magnitude of the acceleration is a minimum

Question

Quizplus · Accepted Answer

The speed is greatest when the potential energy is zero, which occurs at the equilibrium position where kinetic energy is maximum. At this point, the magnitude of acceleration is minimum.
