Unformatted text preview: stool two different ways, first as a cylinder with radius R and then as a hoop with radius R. Now take the average of theses two calculations and use this value as your moment of Inertia. M is your actual mass (ignore the mass of the stool) and R is measured several centimeters above your waist. 2 5. When looking down on a spinning wheel that is held parallel to the ground (the wheels axle is perpendicular to the ground) you see that the wheel is rotating in a counter clockwise direction. What is the direction of the wheels angular momentum vector relative to the ground? Can you think of a way to use your right hand (a right hand rule) to determine the direction of the angular momentum vector for any rotating object?...
