Emmy is standing on a moving sidewalk that moves at +2 m/s. Suddenly, she realizes she might miss her flight, so begins to speed up, but then she hears over the PA system that her filght is delayed. A 3 The acceleration versus time graph shows Emmy's N acceleration during the 5 s time interval in which all of the events occur. In the velocity versus time graph, construct a plot of Emmy's velocity over this same time period. Acceleration (m/s?) O -3 6 -5 -6 0.0 1.0 2.0 3.0 4.0 5.0 Time (s) N O Velocity (m/s)N O Velocity (m/s) -2 -3 -4 -5 -6 3.0 4.0 5.0 0.0 1.0 2.0 Time (s) Assuming all the values given are exact, what is Emmy's velocity at a time of 3.79 s? Enter your answer to at least three significant digits. m/s
