[QUOTE="lavalamp3773, post: 2008660, member: 728094"] Hm, so this question seems eerily familiar. Probably because I already answered it when someone else asked. Here I get the formula: http://answers.yahoo.com/question/index;_ylt=AswRXJJv8VWzYL8ig6vpR8fsy6IX;_ylv=3?qid=20090929002846AAjt6z0 And here I get the answer for the specific case of R = 3312: http://answers.yahoo.com/question/index;_ylt=AgddLpwVsuUR8Ul6sIKwbnHty6IX;_ylv=3?qid=20090929021225AARPXIw&show=7#profile-info-aY0DMaZraa If you don't care about how to get the answer, then it is: v = 22,800 m/s to three significant figures. But you should care, so I advise you to read my answers in the above links. [/QUOTE]
