Question

the graph above describes the motion of a student walking on a sidewalk. during which segment is the student walking the fastest? a b-c b c-d c all of the segments have the same velocity. d a-b

Explanation:

Step1: Recall velocity - slope relation

Velocity is given by the slope of a position - time graph. Steeper the slope, higher the velocity.

Step2: Analyze each segment

For segment A - B, it has a positive slope. Segment B - C has a slope of 0 (constant position). Segment C - D has a negative slope and is steeper than A - B.

Answer:

B. C-D
