Question

use the image to answer question. during which segment is the vehicle speeding up while moving forward? a e b d c b d a e c

Explanation:

Step1: Analyze velocity - time graph basics

In a velocity - time graph, positive velocity means moving forward. An upward - sloping line indicates speeding up.

Step2: Check each segment

Segment A has a positive slope and positive velocity. Segment B has zero slope (constant velocity). Segment C has a negative slope (slowing down while moving forward). Segment D has negative velocity (moving backward) and positive slope (speeding up while moving backward). Segment E has negative velocity (moving backward) and zero slope (constant speed while moving backward).

Answer:

D. A
