A 100-gram steel marble traveling at 5 m/s [Right] collides with a target sphere at rest. The magnitude of the force between the marble and the sphere is given by F = √2kFt-k²² where Fmax = 10.0 N and the constant k = 500 N/s. The force is graphed vs. time at right. The curve forms a semicircle. 83) The collision begins at time t = 0 when the force between the marble on the sphere increases from zero. The collision ends when the force decreases to zero again. How long does the collision last? 841 The impulse ims At = 0.04 s F Fmax

Among the many books sbe urote were Eichmann in Jerusalem, On Revolution, and The Origins of Totalitarianism. Editor's Insert During the Second World War. the Germans invaded Denmark in April, 1940. In the beginning of her essay, Hannah Arendt explains that of the four countries almost completely immune to anti-Semitism- Denmark, Sweden, Italy, and Bulgaria Denmark challenged its German masters directly. As soon as the German authorities talked about forcing Jews to wear the yellow badge,' the Danes replied that all Danish citizens, including the King, would be wearing it the next day if the policy were carried out. In addition, all Danish government officials threatened 舌は the German authorities with their immediate resignation if the Germans started to implement any anti-Jewish actions. The following excerpt from Eicbmann in Jerusatem shows how the Danes sabotaged the German plan to carry out the mass extermination of the Jews. only 2タカ人の What happened then was truly amazing; compared with what took place in other European countries, everything went topsy-turvey.

Topic Agree or Disagree: Help from the local community is crucial for raising children POINTS → discipline、safety、working parents、privacy 「肯定意見」 Iagree with the statement that help from the local community is crucial for raising children. There are two reasons to support this contention: the promotion in working for parents and the respect of discipline. These days, almost all the companies in Japan are facing the problem which is how they treat their employees who have children. In fact, these people, especially women, have difficulty in working. What the matters worse, many of them are forced to quit their job because of raising children. To deal with this problem, it is necessary for the local community to help parents raise children. Moreover, help from others will lead to promote the rate of women who continued working after childbirth. In other words, thanks to help from the local society, Japanese companies can improve their working environment. In addition to this, children will be sociable and polite if they are taken care of by another person of family. Also, children will realize the importance of cooperation with others. For these reasons, I strongly believe the local society should do more for parents who raise children.
