Question

A velocity vs. time graph for an object is shown. Which parts of the graph represents the object moving at a constant, positive acceleration? W and X X and Y Y and Z W and Z

Answer 1

Graph is missing please upload

Answer 2

The graph is missing.

Let me answer the question by explaining how to.

Its a graph of velocity vs time.  X-Axis will have time and Y axis will have velocity at given time.

1. Constant speed

In the graph where height of the graph is constant from point A to point B. That means velocity did not change with respect to time.

That is acceleration = 0 and constant speed.

2. Positive acceleration.

Positive acceleration means, velocity increases with respect to time. So in the graph you will find height of line increases from previous point.

If the initial point is A from where line graph is always increasing. Point B is place where line graph is either same as previous point or decreasing.

Then AB represent the positive acceleration.
