Question

select the correct answer. which segment of the graph shows a decreasing velocity? time (s) a. a to b b. b to c c. c to d d. d to e

Explanation:

Step1: Recall velocity - time graph concept

On a velocity - time graph, a decreasing velocity is shown by a segment where the curve is sloping downwards.

Step2: Analyze each segment

Segment A to B is horizontal (constant velocity), B to C is sloping upwards (increasing velocity), C to D is sloping upwards (increasing velocity), and D to E is horizontal (constant velocity). There is no segment in the given graph that shows a decreasing velocity. But if we assume the options are based on some mis - understanding and we consider the general principle, if there was a decreasing velocity segment, it would be a downward - sloping part. Since no such real segment exists here, we assume the closest concept application. If we consider the nature of slopes, a horizontal segment after an increasing one can be thought of in a relative sense where the 'rate of increase' has stopped which is a form of 'decrease' in the rate of change. Among the options, D to E is the one where the upward trend stops.

Answer:

D. D to E
