A simplified model of athletes running the 100 m dash assumes that they run with constant acceleration of 4.7 m/s2 up to a distance of 11.60 m, and then maintain a constant speed until they reach the finish line. Draw a sketch of the problem and a v-t graph. What is the final speed of the runner?

need some help with this please and thanks
