In Section 9.8, we discussed the path of an object that is dropped from a very tall stepladder above the equator. (a) Sketch this path as seen from a tower to the north of the drop and fixed to the earth. Explain why the object lands to the east of its point of release. (b) Sketch the same experiment

Using Figure 85 as a starting point, suppose the premium curve for black house- holds is an inverted U and lies above the white curve for a white population in the range 5060 whites, but below the white curve for a larger white population. In other words, the two premium curves intersect at 60 white
