Question: Time/position DE y = 1.7049x 20 Position (m) 15 10 5 15 20 Time (s) . What is the slope of the best fitting straight

Time/position DE y = 1.7049x 20 Position (m) 15 10 5 15 20 Time (s) . What is the slope of the best fitting straight line? What is the uncertainty (standard error) in this slope? Do you think that a straight line produces a good fit to the data? 1.7049, the standard error is 0.08803351, yes a straight line fits best . What is the average speed and the uncertainty in the average speed of the object? . Is the object moving with approximately constant speed, or is its speed increasing or decreasing? Justify your answer.
