Question

which segment of this graph shows a decreasing velocity?
time (s)
a. a to b
b. b to c
c. c to d
d. d to e
e. e to f

Explanation:

Step1: Recall velocity - time graph concept

On a velocity - time graph, a decreasing velocity is shown by a segment where the velocity (y - value) is getting smaller as time (x - value) increases.

Step2: Analyze each segment

• Segment A to B: Velocity is constant (horizontal line).
• Segment B to C: Velocity is increasing (line with positive slope).
• Segment C to D: Velocity is increasing (line with positive slope).
• Segment D to E: Velocity is constant (horizontal line).
• Segment E to F: Velocity is decreasing (line with negative slope).

Answer:

E. E to F
