物理基礎の問題です 答えは 6.（１）０．２４ (2)1.4×10 7.(1)40√3 58N です。解き方を教えてください。

軽いつる巻きばねの一端を天井に固定し、他端に質量 2.0kgのおもり A をつるしたら長さが0.38mになり、質 量3.0kgのおもりBをつるしたら長さが0.45mになった。 0.38 0.07. 007 6. 重力加速度の大きさを9.8m/s2とする。 (1) ばねの自然の長さは何mか。 (2) ばね定数kは何N/mか。 7. あらい水平面上に質量10kgの物体を置き, 糸 をつけて水平から30°上向きに 80Nの力で引いた が,物体は動かなかった。 重力加速度の大きさを · 9.8m/s2として、物体にはたらく摩擦力の大きさ F[N], 垂直抗力の大きさ N [N] を求めよ。 なお はそのままでよい。 -0.14 10kg 0.38m 41 0.45mg AO l l l l l l l l l l l 12. T 160. 80 N 8791 30° T1 fo 00000000000 B 40 石を通過 問題の 以下 (a+ 品 (2) 距 (3)

この極限はなぜ無限に発散するのですか？ゼロだと思いました。

7³ → 1 ±02-1 =lim +46 ±∞ (複号同順) H

物理の問題です。a-tグラフの読み取りかたがよくわからないです。 ①〜⑤の解説していただけだら幸いです。

3. (各5点) 外力によって水平面上の直線を移動する 100kgの物体の時間一加速度のグラフ (図) を見て、 最初 (t=0s で) 静止していた物体の運動について答えよ。 ただし重 力加速度は10m/s2 とし、 外力は物体が移動する直線方向に働く。 外力、 重 力、地面との摩擦力以外は無視できるとする。 時間一加速度のグラフ N 物体の加速度(m/s2) 2 -4 0 5 10 15 20 25 30 35 40 245 50 55 60 時間 (s) NE-ELOS (0) 5*5 (3) () (0) ① 最高速度は (13). (14)×10(15; +-) (16) m/s である。 7.0×10+1 mls ②t=60s の時の速度は (17). (18) ×10(19: +-) (20) m/s である。 4.0x10+1m/s S (3) ③t=0s から t=60s の間に進んだ距離は (21). (22)×10(23;+.-)(24)m である。 3.0x10+m ④t=20s の時、物体に働く直線方向の合力は (25) (26) ×10(27;+) (28) N である。 4.0×10+2N ⑤ 動摩擦係数 0.4で常に同じ大きさの摩擦力が働いているとするとき、 t=0s か らt=60s の間に物体に働く外力がした仕事は (29) (30)×10(31、+、-) (32) J である。 +6 1.3 x 10*6 J つんこをさら
