Question

Hi all, I need help with parts B, C, and D.  Thanks in advance.

For Part A, I got 44 cm/s for segment 1; 20 cm/s for segment 2; and 28 cm/s for segment 3.

Below are life size images of three segments of paper ribbon like those you used in tutorial. (Segments like these are generated by attaching a paper ribbon so that it drags behind a cart and through a tapping device, the tapper leaves dots as it taps on the ribbon at constant rate, every of a second.) USe a ruler to determine the speed of the object that generated each of the paper segments(in cm/s). Write each speed under the corresponding image above. On the position-time graph below left, graph the motion of the object that generated each segment assuming overall uniform velocity. Match each segment to its place on the graph. (There are many possible correct graphs.) On the position-time graph below right, graph the motion of the object that generated the segment assuming that all three segments are part of the same overall motion. Match each segment to its place on the graph. (Again, There are many possible correct graphs.) On the position vs. time graph at right: What do the three different lines represent? What is the interpretation of the slope of each line? What is the interpretation of the intercept of each line (the place where it crosses the vertical axis)?

Explanation / Answer

I can only help you with D.

1. DIfferent lines represent diifferent displacements of the body with respect to time

2. Slope of each line represents velocity of the body

3. Intercept means starting point of the body
