Question

To see the acceleration graph, go to the x vs. t graph in “Frame 3” and change the vertical axis to ax. Now step through the movie again. Observe the vx versus t graph and the ax versus t graph side by side. Describe the shapes of the two graphs and describe how they appear to relate.

Answer 1

Answer:

The ax versus t graph stays in the range of 2.5 to 3 m/s2 for the first 2 seconds or so, and then it drops quickly to just below 0 m/s2. This corresponds well with the slope of the vx graph: relatively constant positive slope for the first 2.5 seconds, and then zero (and even negative) slope afterwards.

Answer 2

Answer:

The ax versus t graph stays in the range of 2.5 to 3 m/s2 for the first 2 seconds or so, and then it drops quickly to just below 0 m/s2. This corresponds well with the slope of the vx graph: relatively constant positive slope for the first 2.5 seconds, and then zero (and even negative) slope afterwards.
