Question

The figure shows a distance vs. time graph of an object with three distinct regions, I, II, and III.  The object's velocity is positive in region(s)
A) I. 
B) II. 
C) III. 
D) no regions

Quizplus · Accepted Answer

In region I, the slope of the graph (i.e. the object's velocity) is positive, indicating that its velocity is positive. In regions II and III, the slope of the graph is zero, indicating that the object's velocity is not positive in those regions.
