If pete (mass =90.00kg) weighs himself and finds that he weighs 30.0 pounds, how far away from the earth is he?

Here we know that mass of the person is 90 kg

His weight is given as 30 lbf

so here we can convert it into Newton as we know that

1 lbf = 4.45 N

Now from above conversion

now we can use this to find the gravity at this height

now we know that with height gravity varies as

so above is the height from the surface of earth

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

cant without the picture! ?
