Chapter 2.4, Problem 40SSC

To determine

To Rank: the graphs according to each object initial position from most positive to most negative position.

Answer to Problem 40SSC

The ranking of a graph from positive to negative is A, C,B and D. Yes, ranking would be different depends on initial position.

Explanation of Solution

Given information:  Here 4 objects position with respect to time shown in a graph.

Concept used:

The object's initial position is seen by the first point on position axis when the value of time is zero.

Calculation:

For object A, initial position is more positive than for C

For object B, the initial point is at origin and for object D,the initial point is on negative position axis.

Yes, ranking would be different if initial distance to origin is calculated. The distance of object A is maximum and decreases for C,D,B.

Conclusion:

Thus, ranking from greatest distance to least distance be A,C,D and B.
