Question

the motions of objects a, b, and c are represented on a position - time graph. observe the lines and rank the speeds of objects a, b, and c from slowest to fastest. tap the fields below to rank the locations in terms of their speed smallest v middlest v greatest v

Explanation:

Step1: Recall speed - slope relation

Speed on a position - time graph is given by the slope of the line. The steeper the line, the greater the speed.

Step2: Analyze slopes of lines

Line C has the least steep slope, line A has a steeper slope than C but less steep than B, and line B has the steepest slope.

Answer:

Smallest v: C
Middlest v: A
Greatest v: B
