A professional skateboarder successfully navigates a 360° full pipe turn. Determine the minimum speed which would be required at the top of the circular loop to make it through
the 1.8-m radius pipe.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

d) physical means can be used to separate the components of air.
