if you're taking it from ILC, so am I, and there are a lot of questions that don't make sense like that... the calculations and the constants are correct, but then they give you ridiculous numbers to deal with that don't make sense...
I typed into my calculator the following : (6.67x10-11)(5.98x1024) and I got 3.98866x1014... I did it several times and came up w/ that number...
So the answer i am submitting is 1000 m than what you submitted... 24 and -11 make 13, how did i get 14?
I used 2 different formulas to find Ek, and got a different number from yours...
I don't know what number you used for the radius, but I used 6378.1 km, which I found off google...
Ek = mv2
Ek = (1500kg)(5000m/s)2
Ek = 3.75 x 1010 J
Ek = -GMm/r
Ek =...
