In the early morning hours of June 14, 2002, the Earth had a remarkably close encounter with an asteroid the size of a small city. The previously unknown asteroid, now designated 2002 MN, remained undetected until three days after it had passed the Earth. Suppose that at its closest approach, the asteroid was 73600 miles from the center of the Earth -- about a third of the distance to the Moon.

(a) Find the speed of the asteroid at closest approach, assuming its speed at infinite distance to be zero and considering only its interaction with the Earth. answer should be in km/s

First off all ,, I believe that you are referring that we are the same person, unfortunately we are not. second this website as I can see from its name is Homework HELP. so if you willing to help do so, or else please don't reply to me. Third, if I know how to solve it I wouldn't have post the question here.

3. First off, we can tell that you are posting from ONE COMPUTER in Jiddah, Saudi Arabia.

Second, there are no proxies indicated for this IP address, and it's not indicating that you are posting from a school or university.

Third, one computer almost always indicates one student. Fooling around by posting with different names indicates that you are trying to fool someone. That's too bad.

Fourth, if all you do is post your entire assignment, with no evidence of thinking on your part, nothing will happen since no one here will do your work for you. But if you are specific about what you don't understand about the assignment or exactly what help you need, someone might be able to assist you. Ask specific questions!
