One of the trade-offs tesla faces is between safety and the maximum range someone can drive an all-electric car before having to recharge it. for example, adding steel to a car makes it safer but also heavier, which results in fewer mileage between recharges. assume that this trade-off is consistent with increasing costs of added safety. draw a hypothetical production possibilities frontier that tesla engineers face that show this trade-off.

Kendra knight took part in a friendly game of touch football. she had played before and was familiar with football. michael jewett was on her team. in the course of play, michael bumped into kendra and knocked her to the ground. he stepped on her hand, causing injury to a little finger that later required its amputation. she sued michael for damages. he defended on the ground that she had assumed the risk. kendra claimed that assumption of risk could not be raised as a defense because the state legislature had adopted the standard of comparative negligence. what happens if contributory negligence applies? what happens if the defense of comparative negligence applies?
