Below is a graph of a gnat flying along a horizontal path. 4 velocity (m/min) 80 0:23:34 60 40 20 time (min) - 20 - 40 10 20 30 40 50 a.) What is the gnat's displacement over 8.0 s? b.) What was the acceleration of the gnat at t = 30 s? Show your work. c.) Describe (in detail) the motion of the gnat through all 8 s
