Find the weight of the object

  1. Oct 2, 2012 #1
    1. The problem statement, all variables and given/known data

    The gravitational acceleration at the International Space Station’s altitude is about 93% of its surface value.

    What’s the weight of a 72 kg astronaut at this altitude?

    2. Relevant equations

    w=mg
    where w is weight
    m is the mass
    g is the gravity's acceleration

    3. The attempt at a solution

    mass is given as 72kg

    I know the station is a satellite in space. but how do i go about finding acceleration? any tips would be helpful.

    What's the 'surface value' of the acceleration due to gravity?

    well i know acceleration due to gravity is 9.81 meters per second every second. Ah so that's what they are asking! I got it! =]
