Question

based on the two graphs you created, do you think the plexiglass is speeding up, slowing down, or falling at the same speed? explain why. refer to both graphs in your answer.
use a line of best - fit to find the acceleration of the falling plexiglass. we can do this by calculating the slope of the speed - time graph. you should have three slopes (one per experiment).
do your speed - time graph and your calculations support leonardo da vincis claim that the acceleration of falling objects is 9.8 m/s², regardless of their weight? refer to your graphs and calculations in your answer.

Explanation:

Step1: Determine motion from graphs

If the speed - time graph has a positive slope, the object is speeding up; if negative, slowing down; if slope is zero, moving at constant speed. Analyze the two graphs to check the trend of speed over time.

Step2: Calculate acceleration

The acceleration \(a\) is given by the slope of the speed - time graph, \(a=\frac{\Delta v}{\Delta t}\), where \(\Delta v\) is the change in speed and \(\Delta t\) is the change in time. Calculate the slopes for the three experiments.

Step3: Compare with Da Vinci's claim

Compare the calculated acceleration values from the slopes of the speed - time graphs with the value \(9.8\ m/s^{2}\). If the calculated values are close to \(9.8\ m/s^{2}\), then the results support the claim; if not, they do not.

Since no actual graphs or data are provided for calculations, we can't give numerical answers but the general process is as above.

Answer:

No specific answer can be given without the actual graphs and data for calculations.
