Problema Solution
an object is 100 pounds when it is at sea level.
Find the value of C that makes the equation true.
(Sea level is 3,963 miles from the center of the Earth.)
Using equation below
w = Cr^-2
Answer provided by our tutors
W = C/r^2
Multiply by r^2:
Wr^2 = C
divide by W:
r^2 = C/W
Square root:
r = sqrt(C/W)
