Question

Below are life size images of three segments of paper ribbon like those from class. (Recall 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 a constant rate, every 1/40th of a second.)

A.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.

B. On the positiontime 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.)

C.On the position-?time graph below right, graph the motion of the object that generated the segments 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.)

D. On the position vs. time graph below:

1. What do the three different lines represent?

2. What is the interpretation of the slope of each line?

3. What is the interpretation of the y-intercept of each line (the place where it crosses the vertical axis)?

Explanation / Answer

D. 1.The 3 lines represent the respective position with respect to time.

2.As slope of each line is constant that means they have constant velocity. Greater the slope, greater is the velocity.

3.y-intercept of each line shows the position at which they are located at time t=0
