Assume that voters are uniformly distributed along a straight line from “far right” to “far left” (however you want to describe each). We have seen that Hoteling’s model predicts that candidates in a two-party system will be positioned in the center. Moreover this would imply policies coming out of a two-party system will be somewhere in the middle. What happens if a viable third party / third candidate is inserted into the mix? What is the equilibrium then? (Assume that...

a stunt driver's car is moving at 24.2 m/s along a straight road. The road comes to an abrupt stop 21.2 m before a drop off. The coefficient of friction of the road is 0.712, and the coefficient of friction of the dirt between the road and the drop off is 0.426. What is the minimum distance at which the driver can behin to apply the brakes and still prevent himselff from going over the edge?
