A mass is suspended vertically from a spring so it is at rest at the equilibrium position.The mass is pulled straight down to an extension x and released so that it oscillates about the equilibrium position.The acceleration is greatest in magnitude and directed downward when the mass is
A) at its maximum upward travel.
B) at the equilibrium point.
C) at its maximum lower travel.
D) somewhere between the equilibrium point and maximum extension.
