Problem

A mass moves along the x-axis following the position vs. time graph provided. During what time interval(s) does the mass have an acceleration of

0 \frac{m}{s^2}

? Time is represented as t. [Figure: Position vs time graph showing curved and linear segments] (A) only from 0 s < t < 3 s (B) only at t = 5 s (C) only from 7 s < t < 10 s (D) only from 0 s < t < 3 s and 7 s < t < 10 s (E) only from 0 s < t < 3 s, t = 5 s, and 7 s < t < 10 s
