Question

The dependent variable is the position (y-axis) and the independent variable is the time (x-axis). This is the measured position of a rock as it falls from the top of a very high cliff and obeys the equations y = 1/2gt². Make sure you label the plot properly. Right click on a data point in the graph and add a “Trend line.” Select a polynomial of order 2. This is a parabolic equation and describes an object falling under constant acceleration. Also check the box that says ‘Display equation on the graph.”   Since the acceleration of gravity is 2 times the coefficient of the x² term, what do you find for the acceleration of gravity. I have the graph, I just need help with the part below the table.

Measurement	Time (s)	Position (m)
1	0	0
2	1	5
3	2	21
4	3	46
5	4	82
6	5	129
7	6	185
8	7	252
9	8	330
10	9	417

Calculate g using your equation. ( do not forget the units)

Coefficient of the x² Term = ____________________                              “g” = ____________________
