この問題はなぜ等速円運動ではないのですか?初速度があるからでしょうか?初速度があるとなぜ、等速にならないのですか?あと、⑵なんですけど、張力が0だとだめだから、張力≧0じゃなくて、張力>0だと思うんですけど、なぜ、解答のようになっているのですか?あと、3枚目なんですけど、青... Read More

右ページの図のように, 長さ(の糸に質量mの物体を結び, 最下点で初速度しっを 問8-3 与えた。 以下の問いに答えよ。 糸が鉛直方向となす角度が0のときの糸の張力Sを求めよ。 物体が1回転するために必要なめに関する条件を求めよ。 この問題では, 物体の高さが変わるため, 物体の速さも変化します。 つまり、この問題における円運動は, 等速円運動ではないのです。 等速でない円運動の場合でも基本的な考えかたは等速円運動のときと同じですよ (1)は「円の中心方向の力のつり合いを考えて, S=mgcosθ」としてはダメです。 物体は静止していない, つまり, 円運動をしています。 円運動をしているということは, 中心方向に加速度が生じていますよね。 加速度が生じているということは, 力のつり合いではなく, 運動方程式を立てて考えなければならないということです。 解きかた (1) 向心力は, 張力Sと, 重力の中心方向成分である-mgcosθとの和 S-mgcos0

1. Introduction In the 1980s, Japanese financial institutions increased their presence in Western financial markets. Japanese financial institutions had close business relationships with large Japanese corporations (interlocking keiretsu business relationships) and suffered few non-performing loans because of the country's steady economic development, making them the soundest financial institutions in the world. Table1 shows the transition in the eredit ratings of major Japanese financial institutions and demonstrates that in 1988, many Japanese financial institutions were given a top credit rating. However, in the 1990s, the financial condition of Japanese financial institutions deteriorated rapidly as a result of an increase in non-performing loans brought on by an economic slump. For example, Figure 1 shows the changes in the balance of non-performing loans that Japanese banks held. At its peak at March 2002 (i.e., the end of FY 2001), this level exceeded ¥40 trillion. Figure 2 clearly indicates the severity of the problem, and Figures 1 and 2 show that, despite disposing of non-performing loans exceeding ¥10 trillion several years in the late 1990s, the balance of non-performing loans stillincreased. In 1997, the financial condition of major banks grew severe, as evidenced by the failure of institutions such as Hokkaido Takushoku Bank, which had a significant standing among major commercial banks, and Yamaichi Securities, one of the four major security corporations. Many financial institutions that survived with government assistance barely escaped bankruptcy. In the past, Japanese banks were subjugated under extremely strict regulations implemented by the Ministry of Finance. In the 1980s, however, financial globalization progressed, increasing the concern that if the regulations did not change, they may promote the hollowing out of domestic markets. Beginning in 1996, the Japanese government advocated Japanese “Big Bang" financial reforms and fundamentally restructured the regulations. These reforms could have becen viewed as a "constructive" approach to financial regulations for a new cconomic environment. On the other hand, the deterioration of the business conditions of financial institutions progressed at a speed and scale greater than what was anticipated. Because the laws that
