[題目]A space ship is far from the solar system and has a large communication
dish. It travels with velocity to the right of 100ms^-1.The ship,dish and fuel
have a mass of 1000kg. The ship encounters a shower of sticky meteorities of
average mass 0.01kg traveling with velocity of 200ms^-1 to the left.There are
1000 meteorities per second hit the dish and stick to it.As the first
meteorite strikes the dish, the rocket engines are fired to eject 10kg of fuel
per second at a velocity to the ship of 500ms^-1 to the left.Calculate the
acceleration of the ship at that instant.
[瓶頸] (寫寫自己的想法,方便大家為你解答)
我試著用火箭問題去想 只是不像一班的火箭問題 太空船是有被撞擊的
用了許多方法算出來答案還是錯 謝謝~
