SOLUTION: b. Suppose that 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.) w=Cr^-2(

Question 134473: b. Suppose that 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.) w=Cr^-2(r=distance)

Start with the given equation

Rewrite as

Multiply

Plug in (this is the given weight) and (this is the given distance from the center)

Square 3,963 to get 15,705,369

Multiply both sides by 15,705,369

Multiply

So the constant is
