A speed versus time graph is shown:

Graph of speed versus time, with speed on the y axis from negative 2 c m per s to positive 2 c m per s-- and time on the x axis from 0 s to 8s. Segment 1 goes from 0,0 to 1,0. Segment 2 goes from 1,0 to 2, 0. Segment 3 goes from 2,0 to 2, 1.5. Segment 4 goes from 2,1.5 to 3, 1.5. Segment 5 goes from 3,1.5 to 4, 1.5. Segment 6 goes from 4,1.5 to 5, 1.5. Segment 7 goes from 5,1.5 to 6, 1.5. Segment 8 goes from 6,1.5 to 6, 0. Segment 9 goes from 6,0 to 7,0.
