Problem

High-speed motion pictures ( 3500 ) of a jumping, 210 flea yielded the data used to plot the graph given in the figure The plot shows the flea’s jumping speed as a function of time. Time is measured from 0 to 2.5 milliseconds on the x-axis. The speed is measured from 0 to 150 centimeters per second on the y-axis. The speed smoothly increases from 0 milliseconds and 0 centimeters per second to 1.5 milliseconds and 130 centimeters per second forming a convex curve. Then the speed stays at this value until 2.5 seconds.. (See "The Flying Leap of the Flea" by M. Rothschild, Y. Schlein, K. Parker, C. Neville, and S. Sternberg in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical take-off angle. Use the graph to answer the questions.
