I have completed the data table and the graphs, but I'm stuck on the calculations for the questions. Can anyone please help and explain the steps I should take? Thank you! Also the `y is being used in place of a y with a line over it to indicate the mean of y.

The data table located in the Lab Report Assistant shows data taken in a free-fall experiment.Measurements were made of the distance of fall (y) at each of the four precisely measured times. From this data, perform the following operations:

Time, t (s)	Dist. y (m)	Dist. y (m)	Dist. y (m)	Dist. y (m)	Dist. y (m)	` y	?	t^2
0	0	0	0	0	0	-	0	0
0.5	1	1.4	1.1	1.4	1.5	1.28	0.177012241	0.25
0.75	2.6	3.2	2.8	2.5	3.1	2.84	0.248997992	0.5625
1	4.8	4.4	5.1	4.7	4.8	4.76	0.224499443	1
1.25	8.2	7.9	7.5	8.1	7.4	7.82	0.318747549	1.5625

1. Complete the table.
2. Plot a graph `y versus t (plot t on the x-axis or abscissa).

3. Plot a graph `y versus t2 (plot t2 on the x-axis). The equation of motion for an object in free fall starting from rest is y = 1?2 gt2, where g is the acceleration due to gravity. This is the equation of a parabola, which has the general form y = ax2.
4. Determine the slope of the line and compute an experimental value of g from the slope value. Remember, the slope of this graph represents 1?2 g. (The equations I got from the spreadsheet by doing a polynomial trendline. For y vs t - y=4.9838x^2 - 0.041x. For y vs t^2 - y=0.1164x^2 + 4.7937x)
5. Compute the percent error of the experimental value of g determined from the graph in step 4. (Accepted value of g = 9.8 m/s2).
