Answer:
See below
Step-by-step explanation:
See the attached image. My calculation seems a bit off from what I expected, but the reasoning might help.
The paper is trailing the dropped object and a mark is made every 0.020 seconds. By measuring the difference between the dots and dividing by the time, we can calculate the average speed at the the final 2 locations. The difference in these speeds is due to acceleration, as shown in the calculation.
My result wasn't what is considered correct for Earth's acceleration of gravity, but I offer possible explanations. Please check my calculations.
