A person sitting on a Ferris wheel rises and falls as the wheel turns. Suppose that the person's height above ground described by the following function. h(t)=21.2-19.7 cos 1.1t In this equation, h(t) is the height above ground in meters, and I is the time in minutes. Find the following. If necessary, round to the nearest hundredth. Frequency of revolutions per minute meters Minimum height above the ground: Time for one complete revolution: minutes X
