A mass is hung at the end of the spring length of 14 cm. The mass was pull down and extend to the quarter of the original length of the springs and released so that it oscillates vertically. If the mass took 0.125 s to go up and down from equilibrium point. Find the acceleration when the displacement is at maximum

You will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. (refer to the walk-through video to locate the online lab within the online textbook).
