Sean got a new yo-yo and noticed that the height of the yo-yo follows a sine or cosine curve. At time = 3 seconds, the yo-yo is at its lowest height of 40 cm above the ground. The string is 62 cm long and one cycle takes 2 seconds. Find an equation that will determine the height of the yo-yo at any time t. You can assume the yo-yo is extended the full length of the string, perpendicular to the floor at its lowest point. a. Find the height of the yo-yo after 20 seconds. b. Find the first time the height of the yo-yo reaches 52 cm above the ground. Calculators Tools CPM Tutorials
