(1)〜(4)の解き方って合っていますでしょうか。また、(5)の問題が分からなかったので教えていただきたいです🙇左が問題、右が解いたものです。

問4 軽いバネの片端を壁に固定し、 他端に質量mの物体をつけて粗い床面に置いた、水平パネ振り子を考 える。 バネが自然長の時の物体の位置を=0とし、 バネが伸びる向きに軸正をとる。 物体は床面から速度 と逆向きの抵抗力-bu を受ける (6は比例定数)。時刻 t = 0 に、 原点にある物体に正の初速度 vo を与える と、バネ定数にがん=だったため、このパネ振り子は臨界減衰振動をした。 この時、任意の時刻 t におけ る物体の位置(t) は右下のグラフのようになり、y=を用いて以下の式で表せる。 (t)=votent 以下の間に、mo, のうち、 必要な記号を用いて答えよ。 (自然対数の底eは数字なので、当然使用可。) (1) 最初に物体の速さが0となる時刻 to を求めよ。 (2) 時刻 to の物体の位置 z (to) を求めよ。 (3) 時刻 to までにバネが物体にする仕事 W を求めよ。 (4) 時刻 to までに床からの抵抗力が物体にする仕事 Wa を、 (3) の結果を用いて求めよ。 (5) 【チャレンジ問題】 前問で求めたW を、 以下の積分を実行することで導け。 rx(to) = to) (-kv)dz = Wa= ・to sto (-kv)dr = √ (-bv) vdt = √ (-bv²) dt 位置 時刻
