Answer» Given : Ferris wheel reaches the maximum height of 9m at 5s and then reaches the minimum height of 1m at 65S To Find : a. What is the period (the length of time to complete one cycle)? b. What is the radius of the wheel? Solution: maximum height of 9m at 5s minimum height of 1 m at 65s Times = 65 - 5 = 60 sec = 1 min Maximum Height to Minimum Height = 1/2 Cycle Time taken for 1/2 cycle = 1 min Time Taken for complete cycle = 1 * 2 = 2 min = 120sec the period (the length of time to complete one cycle) = 120 Sec or 2 min Vertical distance = 9 - 1 = 8 m Diameter = maximum height - minimum height Diameter = 8 m Radius = 4 m LEARN More: Florence is riding a Ferris wheel.
