An object is executing simple harmonic motion.What is true about the acceleration of this object? (There may be more than one correct choice.)
A) The acceleration is a maximum when the displacement of the object is a maximum.
B) The acceleration is a maximum when the speed of the object is a maximum.
C) The acceleration is a maximum when the displacement of the object is zero.
D) The acceleration is zero when the speed of the object is a maximum.
E) The acceleration is a maximum when the object is instantaneously at rest.

In simple harmonic motion, acceleration is maximum when displacement is maximum (A), and zero when speed is maximum (D). Acceleration is also maximum when the object is at rest, as it is at maximum displacement (E).
