Question 164386: I need help with this question as soon as possible. I have been working on it and cannot figure it out.
The weight of an object follows this equation: where C is the constant, r is the distance from the center of the earth (3963 miles). Using the value of C = 1570536900, determine how much an object would weigh in Death Valley (282 feet below sea level).
Thank you!

:
since we have the radius in miles we have to convert 282 ft to mile:
= .05341 mi below sea level:

the reciprocal of r will take care of the neg exponent

Substitute for C and r, subtract the dist below sealevel

w = 100.00273 lb; Means 100 lb weight in death valley is slightly heavier

A lot numbers to crunch here. Check my math on your calc.
