Write yоur аnswers tо the fоllowing questions on а sepаrate piece of paper. You do not need to write the questions down again, just the answers clearly labeled by part (a), (b), etc. Then upload your submission just as you do for homework assignments. You need to experimentally determine the acceleration due to gravity g and you have an apparatus that holds a small steel sphere above a recording plate, as shown above. When the sphere is released, a timer automatically begins recording the time of fall. The timer automatically stops when the sphere strikes the recording plate. You and a lab partner are able to measure the time of fall for different values of the distance D shown above and records the data in the table below. These data points are also plotted on the graph shown below. (a) On the grid above, sketch the smooth curve that best represents the data. Use these data for distance D and time t to produce a second graph from which the acceleration g due to gravity can be determined from the slope of a straight line. Hint: Remember that the equation for a straight line is y = mx + b If only the variables D and t are used, what quantities should you graph in order to produce a linear relationship between the two quantities? (For example, would you plot t3 on the y axis and D^2 on the x-axis? Would you plot the square-root of t on the y axis and D3 on the x-axis? Or would you need to plot some other variation of D and t?) Create a graph similar to the one below, plot the data points for the quantities you have identified in part (b), and sketch the best straight-line fit to the points. Label your axes and show the scale that you have chosen for the graph. Using the slope of your graph in part (c), calculate the acceleration g due to gravity in this experiment. State one way in which another student could improve the accuracy of the results if the experiment were to be performed again. Explain why this would improve the accuracy.
