One-Dimensional Kinematics

•  Take the cursor and highlight an area of the x(t) plot when the cart was in motion by clicking on the curve at an integral time, e.g. 2 s, and dragging the cursor to another integral time, e.g. 6 s.  In the lower left-hand corner of the plot, the magnitude of the displacement, Δx, is displayed. Copy and paste this plot into the appropriate place in Question 2 of the worksheet, making sure that the displacement and the data are readable.

•  Highlight the same area of the v_x(t) plot as you did for the x(t) plot.  Use the Integrate function to find the area under the velocity curve.  It is the unnamed button located between the “STAT” and “R=” buttons on the upper toolbar.  The magnitude of the area should be close to the value you got above for the magnitude of the displacement.  Copy and paste this plot into the appropriate place in Question 2 of the worksheet, making sure that the value of the area and the data are readable.

•  Make the integration disappear by clicking on the cross in the upper right-hand corner of the integral data box.  Select the Examine toolbar button labeled “X=”.  The information goes away if you click on the same function button.  Move the vertical bar along the velocity curve to an integral time, e.g. 4 s.  Copy and paste this plot into the appropriate place in Question 3 of the worksheet, making sure that the value of the velocity and the data are readable.

•  Undo the Examine function by clicking on the button again.  Select the x(t) graph, and click on the Tangent function labeled “M=”, just to the right of the Examine function.  Move the tangent cursor to the same time as you did for the previous step. The tangent (slope) should be close in value to the velocity at your chosen time.  Copy and paste this plot into the appropriate place in Question 3 of the worksheet, making sure that the value of the slope and the data are readable.
