Jane: Risa: Jane: Risa: Jane: Risa: Jane: Risa: Jane: Risa: I was woken up by the earthquake this morning, and couldn't go back to sleep after that. Nothing fell on the floor or was damaged, but definitely it was a big one! I was scared! Yeah, it woke me up, too. I haven't felt one like that in a while, but I think I was too used to those shakings. I went to sleep right after. Weren't you scared, Risa? Yes, but just a little. I think I'm afraid of a really big one, like the one in Tohoku in 2011, anyway. You know, you can't be just scared ( ) preparing for disasters, Jane. Do you know what to do in an earthquake? There are almost no earthquakes in your country, right? No, I haven't experienced one in the U.K. Can you tell me what to do? Sure. The first priority is your safety. Hide under a desk or table to protect your head. Stay there until the earthquake stops. Then be prepared to move to a safer place. I'm sure we'll do some simulations in the evacuation drill held at school next Monday. We'll learn there what's important to do during an earthquake. Wow! That sounds great. I'm looking ( 1) the drill now. Maybe we can get "Moriyama-ku Evacuation Map" after the drill. It shows you (in, where, should, you, a disaster, go ). Jane: Risa: Oh, I'm glad to know that. You should make an emergency kit, too. Our family has made one each and put them near their bed. I see. Can you tell me how I should make it? Well, I'll send you an email later then.

2番と3番の解き方を教えてください! よろしくお願いします。

例題 10 摩擦のある斜面上での物体の運動 右図のように、傾きの角30°のあらい斜面上に,質量 14.0kgの物体を静かに置くと、物体は斜面上をすべりお りた。斜面と物体との間の動摩擦係数を0.20 とする。 (1) 物体にはたらく力を矢印で示せ。 (2)物体にはたらく動摩擦力の大きさはいくらか。 (3) 物体の加速度の大きさはいくらか。 SP 運動方程式の立て方・解き方 ① 着目する物体を決める。 (2 着目する物体にはたらく力をすべて描く。 座標軸を決める(一直線上の運動の場合, 物体が運動する向きをx軸の正の向き, それに垂直な方向を軸とするとよい)。 ④力の矢印をx軸方向, y 軸方向に分解する。 ⑤ 物体が加速度運動をするときは,運動方 程式を立てる (静止または等速直線運動の 場合は力のつり合いの式を立てる)。 (4 6 すべての物体について立てた式を連立方 程式として解いて, 力や加速度を求める。 センサー 13 動摩擦力F'=μ'N は物体 の運動する向きと逆向きに はたらく。 物理の問題には独特の表現が用いられる場合があるので ④ センサー 14 力を互いに垂直で適当な2 方向に分解して, それぞれの 方向で運動方程式を立てる。 センサー 15 運動する向きを正の向きと して, 仮に加速度を正の向 きに書き込む。 図を見なが ら、物体の運動方向にはた らく力のすべてに正負をつ けて, その合力を求め, 運 動方程式を立てる。 ①② 20 y 例傾きの角のなめらかな斜面上に置 かれた質量mの物体の運動 3 mgsinoy N 解答 (1) 物体にはたらく力は, 斜面からの垂直抗力と動摩擦 力, および重力である。 これ らを描くと、右図のように なる。 (2) 物体にはたらく力を,斜面 に平行な方向と斜面に垂直な 方向に分解する。 斜面に垂直 な方向の力のつり合いより, 垂直抗力の大きさをN〔N〕 と すると, mg mgcoso 130° >>46 130° 2 130° 垂直抗力 慣れよう。 mg 軸方向には力 のつり合いの式 y ma=mgsine ⑥ 力と加速度がわかると,さらに等加 速度直線運動の式を利用して, 位置. 速度時間を求めることもできる。 47 48 N-mgcose = 0 x軸方向には運 動方程式 N 重力 1309 動摩擦 4.0×9.8N N=4.0×9.8cos30° F = pl ・動摩擦力の大きさをF'とすると, F' = 0.20 N したがって, F'=0.20×4.0×9.8cos30°=6.7816≒ 6.8[N]) (3) 物体の斜面に平行な方向の運動方程式は、 斜面に沿って 向きを正として, 加速度の大きさを α 〔m/s-〕 とすると, 4.0a=4.0×9.8 sin 30° - 6.78 ゆえに, a = 3.205≒3.2 [m/s ]
