btw, that is already accounted for here:
Leaving margin for error, I can say with certainty that the weight of the average person will be approximately 826.59 Newtons. (YES, Google it. The SI unit of weight is Newton, not mass)
Or, to use your extremely weird scale of stating weights in mass equivalent, 84,289.46 grams. Can't vouch for accuracy, may vary between 84,280 and 84,300 grams.
To clarify, (I know some basic Physics)
Mass is universal. Same everywhere. SI unit is kg - kilogram.
Weight varies. SI unit is Newton.
This one is a little weird answer:
Centripetal_force 1 = centripetal_force 2
84,000 g * (464 m/2)^2 / 6,371,000 m = mass * (463.2 m/s)^2 / 6,371,000 m
mass = 84,290.4 g
I just corrected that here:
Centripetal_force 1 = centripetal_force 2
84,000 g * (464 m/2)^2 / 6,371,000 m = mass * (463.2 m/s)^2 / 6,371,000 m
weight (in grams) = 84,290.4 g
The question clearly states:
Please provide the answer in grams and show your work!
There is no problem is weight is stated in grams just because SI unit happens to be Newtons.
That said, I still think the answer is 28,257,600,000 grams..jambola2 is right.
and this should be:
Reduction Increase in weight = Change in centripetal force = m(V^2)/r - m(v^2)/r = 84(464^2 - 0.8^2)/6,371,000 = 2.83861407
