20 15 v1(t) 10 Two objects move forward along a straight track. for 10 seconds. Object 1 speeds up as it travels. Its velocity function is the increasing line graphed above, labeled v1(t}. Object 2 travels at a steady pace. Its velocity function is graphed above. labeled v2(t). The following questions refer to the graph above. Refer to the graph and information above. During the time interval [0,7] how much greater is Object 1's displacement than Object 2's displacement
