1 Displacement and Acceleration from vt graph Vx (W5) Velocity vs. time graph of an object moving in 1D. xi; = l}. lal {total 5 points) You learned that slope of the v-t graph is acceleration. {i} {2 points] Compute the accelerations of the first segment, Let 1 to 45, and the second segment, i.e., 4 to ? seconds. {ii} {1 point} Did the acceleration increase in the second segment? {iii} {1 point] Is velocity still increasing in the seoond segment? Read the graph to answer it. {iv} {1 point} Can velocitv be still increasing when acceleration decrease? lb] {5 points) lIlou learned that area under v-t graph is displacement. What is the approximate displacement between 4 s and 12 5 based on the above graph? {Notice there is negative displacement after 115}. Show the triangles and rectangles between those times on the above graph you used to compute the area
