Unformatted text preview: 10.90: Angular momentum is conserved, so I 0 0 = I 2 2 , or, using the fact that for a common mass the moment of inertia is proportional to the square of the radius, 2 2 R020 = R2 2 , or R0 0 = ( R0 + R ) 2 ( 0 + ) ~ R02 0 + 2 R0 R 0 + R02 , 2 where the terms in R and 2 have been omitted. Canceling the R0 0 term gives R R = - 0 = -1.1 cm. 2 0 ...
