Answer 1

can you provide a relevant equation maybe?

Answer 2

Answer 3

W=k/d^2

Answer 4

117=k/3978^2

Answer 5

k=1851464628

Answer 6

what is k?

Answer 7

w = work i presume?

Answer 8

shouldn't you use the universal gravitational formula for this problem? (haven't taken physics for a little)

Answer 9

w=weight

Answer 10

no, weight is just mass times gravity w=mg

Answer 11

I am asking for help from my professor this is what she is giving me

Answer 12

what's k in the formula

Answer 13

not the number, what does it stand for?

Answer 14

Answer 15

ohhhhhhh

Answer 16

k = 1851464628

Answer 17

w = 1851464628/284^2

Answer 18

booya there ya'go i think

Answer 19
