CHECKPOINT: apple Key: Answers may vary. Score: 5 out of 5 Comment: Graded: 5 points by Chen, Shih-Yuan on Friday, September 9 2016 06:03 PM EDT. Complete the data table below. Note : You must enter values in the first three columns of the data table to 5 significant figures to avoid rounding off errors. Data Table 1: time t (s) t avg (s) v (m/s) a (m/s 2 ) 0.68366 0.68366 .89741 0.89741 0.79053 0.79053 .23392 0.23392 .94101 0.94101 0.91921 0.91921 1.1467 1.1467 7.0944 7.09 .95414 0.95414 0.94758 0.94758 3.8080 3.8080 93.822 93.8
Procedure A: Calculating the acceleration From this point forward please round your calculations to the WA default value of 3 significant figures. What is the average acceleration from your data table? .97397 0.97397 0.96406 0.96406 2.5214 2.5214 -78.072 -78.1 1.0015 1.0015 0.98776 0.98776 1.8135 1.8135 -29.867 -29.9 1.0258 1.0258 1.0136 1.0136 2.0601 2.0601 9.5135 9.51
Procedure B: Plot of velocity versus time Use Excel to create a graph of velocity versus time. Use the trendline option to draw the best fit line to your data and determine the average acceleration.
What is the percent error between the experimental value of the average acceleration and the accepted value of the acceleration due to gravity (9.81 m/s 2 )? %
Does your percent error indicate that your experimental value of g agrees with the accepted value? (Consider the value of your percent error exactly as you have entered it. Enter 'Yes' if the percent error is less than or equal to 10%. Otherwise, enter 'No.')
