Anne Fibian is a frog who grabs onto a paddle wheel of a riverboat. The horizontal axle of the wheel is at water level. She begins her journey at the top of the paddle wheel clinging tightly to the paddle. The wheel is slowly spinning at one revolution every 6 minutes. This means that Anne is underwater 3 minutes during each rotation/revolution. Time is measured in seconds which means that the wheel is turning through 1 degree per second. The height above the surface of the water is measured in meters and may be either positive (above the water) or negative (below the water). The distance from the vertical axis (measured in meters) of the wheel may also be either positive (right of the vertical axis) or negative (left of the vertical axis).
