Physics Questions about periodic motion?

A stone attached to a spring is oscillating vertically.

What is the direction of the stone's acceleration when it is at the lowest point of oscillation?

At what point in its oscillation does the stone have the greatest downward acceleration?

At what point does the stone have an acceleration of zero in its downward motion?

At what point does the stone have its maximum upward and downward velocities?

What causes the stone to move through the midpoint of its oscillation?

    It's down

    In the extremal parts

    n the equilibrium point (A = 0)

    In the equilibrium point, too

    A Force of the string, F = -kX, is "restauradora"
