An athlete is running in a cross-country event. Starting from rest, the athlete accelerates at 0.50 mls2. After 10 seconds of acceleration the athlete has reached her top speed. Unfortunately, after 200 seconds of running at top speedr the athlete begins to get tired and starts to slow down. She slows down to 2.50 m/s over a 15 second time period. She then maintains this slower pace until she crosses the nish line 125 seconds later. To be clear. 10 seconds of acceleration, 200 seconds of running at top speed, 15 seconds slowing down, then 125 seconds running at 2.50 mls. YOUR TASK is to create BOTH a position-me and velocity-time graph for this athlete's race. 1) Create a graph of the position-versus-time and the 1Irelocityr-'rrersus-time for the runner. Clearly label bath )( and y axes with appropriate units. {2 marks per graph). 2) Use your graphs to determine the total displacement of the athlete. {2 marl-rs) Upload your graphs and typefshow all work done to solve this
