You measure the velocity of falling object at several times given in the table below. Time (s) Velocity (m/s) 0.00 0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 0.90 1.00 The acceleration is the slope of the fit line. Use the Data Analysis ToolPak in Excel (or any other linear regression tool) to determine the acceleration and its uncertainty from the slope of the fit line and its standard error.
