[領域]角動量守衡 (題目相關領域) [來源] 普物習題 (課本習題、考古題、參考書...) [題目]An asteroid of mass 1.4*10^5kg , traveling at a speed of 33 km/s relative to the Earth, hits the Earth at the equator tangentially, and in the direction of Earth's rotation. Use angular momentum to estimate the percent change in the angular speed of the Earth as a result of the collision. find 變化量角速度/角度度 [瓶頸] (寫寫自己的想法,方便大家為你解答) 我的列式是 ((5小Mv+2MR角速度)/(2MR+5小MR)-2拍/86400)*86400/2拍 可是我算出來是0耶 -- 硬碟的容量~決定宅的力量! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.123.222.193
