Question

select the best description for the graph displayed below:
a constantly decreasing positive velocity; constant negative acceleration
b constantly increasing negative velocity; constant positive acceleration
c constantly increasing negative velocity; constant positive acceleration
d constantly increasing positive velocity; constant positive acceleration
e constantly decreasing positive velocity; constant negative acceleration

Explanation:

Step1: Analyze the velocity - time graph

In the given v - t graph, the velocity (v) values are positive as the graph is above the t - axis.

Step2: Determine the slope of the graph

The slope of a velocity - time graph represents acceleration. The slope is positive and constant as the graph is a straight line with a positive slope. As time (t) increases, the velocity (v) is also increasing.

Answer:

D. constantly increasing positive velocity; constant positive acceleration
