Question

five stages - labeled a, b, c, d, and e - of an objects motion are represented by the position - time graph below. during which stage(s) does the object have a negative velocity? tap on the buttons below to answer. select all that apply.

Explanation:

Step1: Recall velocity - position - time relation

Velocity is the slope of the position - time graph, $v=\frac{\Delta x}{\Delta t}$.

Step2: Analyze slope of each stage

For stage A, the slope is negative as position decreases with time. For stage B, slope is zero (constant position). For stage C, slope is negative as position decreases with time. For stage D, slope is zero (constant position). For stage E, slope is positive as position increases with time.

Answer:

A. Stage A, C. Stage C
