Problem

An object starts at the origin and its velocity along a line vs. time is graphed. Which one of the following choices best gives the proper interval(s) of time for which the object is moving away from the origin? [Figure: Velocity vs time graph showing positive velocity from 0-3s, negative velocity from 3-5s, and positive velocity from 5-9s] (A) Only for times 0s<t<3s0 s < t < 3 s (B) Only for times 0s<t<5s0 s < t < 5 s (C) Only for times 3s<t<5s3 s < t < 5 s (D) Only for times 0s<t<7s0 s < t < 7 s (E) For times 0s<t<3s0 s < t < 3 s and 5s<t<9s5 s < t < 9 s
