基本例題 16 2 物体の運動 ➡77 定滑車に糸をかけ, その両端に質量Mとmの物体 A, B をつる す。Bは地上に,Aは高さんの所にある。 糸や滑車の質量を無視 し,M> m, 重力加速度の大きさをg とする。 物体Aを静かには なして降下させるとき, 次の各量を求めよ。 (1) Aの加速度の大きさα (2) Aをつるしている糸1の張力の大きさ T (3) 滑車をつるしている糸2の張力の大きさS (4) Aが地面に達するまでの時間 t と, そのときのAの速さ -g h == at² & t=₁ n=1/2zat v=at より v= M-m M+m a= 2(M+m)h √ (M-m)g = 指針 A, B は1本の糸でつながれているので, 加速度の大きさαも糸の張力Tも等しい。 各物 体ごとに, はたらく力の合力を求め, 進行方向を正としてそれぞれ運動方程式を立てる。 解答 (1),(2) A, B にはたらく力は右図となるので,運動方程式は A: Ma=Mg-T B: ma = T-mg M-m これより, α, T を求めると -g T=- g M+m (3) 滑車には張力Sと2つの張力 Tがはたらいて, つりあうので S=2T=- 4Mm M+m (4) Aが地面に達するまでに, A はん進む。 2h a 2Mm M+m 2(M+m)h 2 (M-m)gh (M-m)g M+m = 解説動画 糸2 \M h B a T 糸1 T L m Mg S A T B Img
