a velocity vs. time graph for an object is shown. which parts of the graph represents the object moving at a constant, positive acceleration? velocity vs time o w and x o x and y o y and z o w and z

Answer

Explanation:

Step1: Recall acceleration - velocity - time relationship

Acceleration is the slope of the velocity - time graph. Positive acceleration means the slope is positive.

Step2: Analyze each part of the graph

In part W, the velocity is increasing with time. The slope of the line in part W is positive. In part X, the velocity is still increasing with time and has a positive slope. In part Y, the velocity is constant, so the slope (acceleration) is 0. In part Z, the velocity is decreasing with time, so the slope (acceleration) is negative.

Answer:

W and X
