Many people know that the weight of an object varies on different planets, but did you know that the weight of an object on Earth also varies according to the elevation of the object? In particular, the weight of an object follows this equation: 2 - = Cr w , where C is a constant, and r is the distance that the object is from the center of Earth. a. Solve the equation 2 - = Cr w for r . Multiply by r^2: Wr^ = C Divide by W: R^2 = C/W Sqrt: R = sqrt (C/W) b. Suppose that an object is 100 pounds when it is at sea level. Find the value of
