1) Graph 1: plot t on the abscissa versus y on the ordinate and (artistically) draw a smooth line through the points. The line need not actually go through each data point.
2) Graph 2: plot t^2 on the abscissa versus y on the ordinate and then perform a linear regression. Remember to plot both the raw data points and the line of best fit (with the two points used to draw it); also show the regression equation and r value on the graph.
3) On graph (1), what does the slope of the line tell you about the velocity of the ball? Be thorough!
4) On graph 2:
a) What does the slope of the line tell you about the acceleration of the ball? Be thorough!
b) Calculate g from the freefall data and the % error (in comparison to 9.81 m/s^2) using the results from the linear regression calculation.
c) What do the values of the y-intercept and correlation coefficient (r) tell you?
Calculate the average fall time and standard deviation using the data above.
Average - 1.5s
Stdev- 1.85s
Use the average fall time and one of the kinematic equations to determine the height of the building.
Add the standard deviation from step 1 to the average fall time from step 2. This represents a “maximum fall time.” Use this time to calculate the “maximum” height of the building.
