But when I did this I said that a tall building was much bigger I said 100 stories with each story being about 9ft so a tall building being like 900ft. (Chrystler Building is 7 and the Empire State Building is 102)<br /><br />To turn ft to m multiply by 0.3.<br /><br />So something like 300m.<br /><br />Good call using 50 instead of 30 to make the math easier. That's what it's all about.<br /><br />My guess was 25 times the mass of earth (like I'll show in my post tomorrow) but 10 or 25. They are both the same magnitude. It's not like we're off by an order of magnitude. They're both good guesses. Good stuff.Brucehttps://www.blogger.com/profile/05397667913578876848noreply@blogger.comtag:blogger.com,1999:blog-7849983335717071080.post-59150542888855247922009-06-24T15:34:20.831-07:002009-06-24T15:34:20.831-07:00Guesstimation 2:

(35kmph)<br />1/2 (10)^2= g*50 (or 30)<br />g= 1 or 1.5<br />kryptn's mass(m directly prprtnl to g) 10 or 7 times earth for same radius.<br />=> 6*(10)^25 or 3.5 * (10)^24Mohit Parikhhttps://www.blogger.com/profile/11651510191396899964noreply@blogger.com
