After 0.5 seconds, the yo-yo is at it’s closest point to the ground, 0.1 metres. After 1 second, the yo-yo is at its farthest point from the ground, 1.7 metres. What is the amplitude of the function that represents the yo-yo’s distance from the ground in terms of the seconds that have passed, and what does it represent?<BR>\n" );
