It takes a satellite 1.76 h to revolve around an unknown asteroid in a circular orbit of radius 540 km.
How long it will take an object without initial speed to reach surface of the asteroid from this orbit?The radius of the asteroid is very much smaller than radius of the orbit and can be considered negligible.
Answer in units of h
The answer is not 0.3963 h.Tell me why!
Many thanks!

此高度处的g‘=4π^2 R/T^2
随着高度降低,g'将逐渐增加,因此此运动并非匀变速运动.
需要进行积分运算.
同学,你得加点油才行哦,你英语还可以,真行!是在国外学习吧,哎,可苦了你,孩子!连问个题目都得用英语说明!(高中只能这么解决,没有其它的办法了。是0.3963 h)要不然,得用到积分的知识了。就是一楼的说法。
