Use Excel to plot a graph of velocity vs. time for the following situations. Include both traces on the same graph. Set your range of time to be 10 seconds, and use a "scatter with smooth lines." All accelerations are constant. v0 (m/s) (m/s2) Trace 1 +20 -2.0 Trace 2 -20 -2.0 2) Use Excel to plot a graph of position vs. time for the following situations. Include all traces on the same graph. Again, use the "scatter with smooth lines" option. All accelerations are constant. Set your range of time just long enough to observe the complete motion (when all 3 traces have crossed the zero position and are moving in the negative x-direction). x0 (m). v0 (m/s) (m/s2) Trace 1 +10 +5.0. -3.0 Trace 2 0 +5.0 -3.0 Trace 3 -10 +5.0. -3.0 3) For each graph, describe ONLY Trace #1 in words. Be specific as possible and be consistent with the plan provided to you in your Chapter 2 Informal Homework. (HINT: describe the trace in a way that one can reproduce it based only on your description)
