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?
