Part II: Instantaneous Speed vs. Time Graph 1. At several (between 10 to 15) values of time 't', determine the slope of the tangent to the distance-time curve using the tangent function of Graphical Analysis. In general, slope means rise/run. In this graph, rise is 'distance' and 'run' is time, so the physical quantity the slope of the tangent line to the distance-time curve gives the instantaneous speed at the time \"t\" as seen from Figure 1 on the instruction sheet. Record v and tvalues in the table below. V (m/s)t (s) 2. Plot 12 vs. I (be sure to label appropriately with correct units) using Graphical Analysis Software. Copy and paste it below. From equation 1 on the instruction sheet, what kind of graphical fit do you expect for a v vs. t graph? 3. Choose the appropriate curve t, and obtain the initial speed v0, and the acceleration a from the results of your curve t. 4. The accepted value of 'g' = 9.8 m/s2 (980 cm/s2). Calculate your percent error. Also do a percent difference between the initial speed obtained from the speed v. time graph and that obtained from the position vs. time graph
