どなたか教えて下さい😭 全部じゃなくてもほんとに大丈夫です

[問題 2] 時刻。からt,の間に質点(質量m)に働く力Fを時間の関数F(t)とする。 質点に力積を与える ことによって質点の運動量の変化が生じることを、運動方程式から導け。 [問題 3] 質量mの球を自由落下(初速度ゼロ)させたとき、空気抵抗が速さいに比例(比例定数k> 0) するとする。終端速度v。は微分方程式を解かずに運動方程式から直接得られることを100 文字内 の文章で説明せよ。また、比例定数nが球の断面積に比例するとき、終端速度v。が球の半径aに比 例することを示せ。ここで、重力加速度をgとする。 [問題 4] 直線上を運動する質点(質量m)に平衡点からの変位xに比例した復元力が働いていた。つぎ の間に答えよ。 (1)変位xの一般解はx = Asin(wot + 8)で単振動することを運動方程式から導け。ここで、復元力 の比例定数をk(> 0)、固有角振動数w。をwo = Jk/mとする。また、A、8は未知定数である。 (2)この単振動する質点に強制力,sin(wt) ( w + w。)を加えたときの強制振動を求めよ。 (3) この単振動する質点に強制力Fosin(wot)を加えたとき、共振することを示せ。 [問題 5] 直線上を運動する質点(質量m)に平衡点からの変位xに比例した復元力および速度に比例す る抵抗力が働くが働いていた。ここで、復元力の比例定数をk(> 0)、抵抗力の比例定数をn(> 0)と する。つぎの問に答えよ。 (1)質点に抵抗が働くときの周期は抵抗が無いときの周期より長くなることを、200文字内の文章で 説明せよ。 (2)強制力の大きさF(t) = Fosin(wt)を加えたとき、復元力の比例定数kと抵抗力の比例定数nの大き さによって、振幅の角周波数依存性が決まる。振幅の角周波数依存性を定性的に200 文字内の文 章で説明せよ。

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
