d二乗x/dt二乗とはなんですか？

解 dx 答 して x=3t2-6t, y=13-9t2+8 で与えられる。 きさが最小となるときの時刻と、そのときのP dy dt よって, 時刻における速度は (6(t-1),3t(t-6)) また =6, -=6t-18=6(t-3) dt =6t-6=6(t-1), -=3t2-18t=3t(t-6) d'y dt2 ゆえに, 加速度の大きさは d2x2 d²y 2 (d) + (²x)=√6² + (6(2-3)}" V dt² dt2 Same d²x dt2 =6√(t-3)2+1 したがって, t=3のとき加速度の大きさは最小となり. 速度は (6 (3-1), 3.3(3-6)) = (12, -27) 答 key 速度 加速 速さ || = ₁ 1 加速度 |α|=₁
