9. Shaun is on a snowboarding trip and is going up and down a mountain that is 700m tall. To start, Shaun rides the chairlift up the mountain, which vertically lifts him 400m over the first 5 min. . The chairlift then comes to an emergency halt and Shaun is stuck for 4 min. * Upon starting up again, the chairlift begins rising at a vertical speed of 100m/min until it reaches the mountain top after 3 more minutes.. . Shaun exits the chairlift and stands still to admire the scenic view for 1 min. . Shaun begins snowboarding down the mountain at a constant vertical speed of 200m/min. . He maintains this speed for 3 minutes. Shaun then starts to uniformly slow down until he eventually comes to a complete stop at the bottom of the mountain after decelerating for 1 minute. Create a displacement/time graph showing Shaun's vertical displacement vs time over the course of his ski run. Include a graph title, axis labels with appropriate units and also label the coordinates of all key points of the graph. 16
