    Moment of Inertia for Earth by superposition

    I=2/5M1R212+2/5(pm4/3piR3)R2-2/5(pm4/3piR312)R23 this equation above has a few errors: the first R is supposed to be R-squared subscript 12 the second to last R is supposed to be R-cubed subscript 12 the last R is supposed to be R-squared subscript 12

    Moment of Inertia for Earth by superposition

    This was a 2 part problem... PART A: calculate moment of inertia of a uniform sphere of mass M and radius R by using the information provided: the moment of inertia of a thin spherical shell at radius R with mass m spinning about its axis is 2/3mR2. I did this by integrating over thin...
