kg*m2 是什么单位?
The moment of inertia of an asteroid rotating about its own axis is 5.00x10的四次方kg*m2. Its angular velocity is 40 rad/s If a force acts on the asteroid for 0.1s, increasing the angular velocity to 48rad/s, find its magnitude.
如果可以的话,请帮我解答.实在想不出答案

M=J(ω1-ω0)/t=5*10^4*(48-40)/0.1=4*10^6 N·m,如果要求力,还要给出力臂长度
其实不错的话是个压强单位 工程上讲的几个公斤的那种
密度单位
我觉得应该是kg*m/s²,也就是N(牛顿)
kg*m2 这个单位貌似没有吧。。
