[題目] 輪子上泥巴的拋射
[領域] 力學 (題目相關領域)
[來源] ISE ANALYICAL MECHANICS 第四章第七題
[題目] Particle of mud are thrown from the rim of rolling wheel
If the forward speed of thewheel is Vo and the radius of the wheel
is b show that the greatest height above the ground that the mud
can go is
b+ Vo^2/2g +gb^2/2Vo^2
At what point on the rolling wheel does this mud leave?
(Note:It is necessary to assume that Vo^2 > bg)
[瓶頸] 本題求最大高度
基本上b+Vo^2/2g 這部分算得出來但總覺得gb^2/2Vo^2這一項怪怪的
如果泥巴本身能在輪子的任何意點選擇出發
起點當然是在輪子朝著正y方向的起點出發(我對y座標公式微分後找到角度帶回去
也是如此)
麻煩各位指點...
