Thread: determine astronauts weight at certain altitude (advanced functions - 3.2)

1. determine astronauts weight at certain altitude (advanced functions - 3.2)

W(h) = We/(1+h/6400)^2

b) what is the astronauts weight at each altitude?
I) 10km II) 4000km

im complety stuck tbh im confused what to do with the denominator (1 + h/6400)^ 2 )

thanks!!

plug in the the two heights you are given.

First $h = 10,000$, then $h=4000$

btw the back of the book says i)817.4N ii) 310.5N

thank you!!

"We", I presume, is the weight of the person on earth. But you don't say what that is.
