Draw a qualitative position-time graph that shows a man who starts at the origin, then runs forward withconstant speed, then stands still for 5 seconds, and finally walks back toward the origin at a slower constantspeed. Now, draw a qualitative velocity-time graph of this motion. (remember a qualitative graph has nonumbers.) Label all axes of your graph.Based on the graph, answer questions 17 and 18:Position (m) vs. Time (s)
