Effect of Elevation on Weight

If an object weighs m pounds at sea level, then it's weight W (in pounds) at a height of h miles above sea level is given approximately by

W(h) = m[4000/(4000 + h)]^2

If Amy Weighs 120 pounds at sea level, how much will she weigh on Pike's Peak, which I'd 14,110 feet above sea level?

Re: Effect of Elevation on Weight

You're not told m but there's a way to calculate it.  Put in h = o (for sea level) and you can find m.

Then you can put h = 14110 . but convert feet to miles first.

Perfect. Copy. Thanks again. Do you have an email address? I need your advice about a new job that I am set to start on March 25. I don't know if I can physically do the job at 58 soon to be 59.
