Where C is a constant, and r is the distance that the object is from the center of the earth.

 

a. Solve the equation above for r.

 

b. I weigh 120 pounds at sea level. If sea level is 3,950 miles from the center of the earth, determine the value of C that makes the equation true.

 

c. Use the value of C you found in the previous question to determine how much I would weigh in
