Consider three force vectors vec(F)_(1) with magnitude 30N and direction 24°, vec(F)_(2) with magnitude 27N and direction -120°, and vec(F)_(3) with magnitude 13N and direction 120°. All direction angles θ are measured from the positive x axis: counter-clockwise for θ > 0 and clockwise for θ < 0. What is the magnitude of the resultant vector vec(F) = vec(F)_(1) + vec(F)_(2) + vec(F)_(3)? Answer in units of N. Answer in units of N.

There are N people in a society (N is a very large number). People are divided into three groups. Each one in the same group earns an identical income but incomes differ between groups. Group A: Poorest 40% of total people B: Richest 10% of total people Income $5,000 $100,000 $20,000 C: All others (neither in Group A nor in Group B) (a) Draw the Lorenz curve for this society. (b) In another society, the poorest 90% of people all earn an identical income and the total income of this group accounts for 40% of the total income of the society. The richest 10% people also earn identical income. Can you tell which society (the two-group vs the three-group society) is more unequal? Briefly explain by using the information in the Lorenz-curve diagrams.
