Calculate the percentage increase in mass

  1. Nov 18, 2012 #1
    1. The problem statement, all variables and given/known data
    Calculate the percentage increase in the mass of an apollo rocket as it escapes from the Earth's gravity at 11.2 kps


    2. Relevant equations

    11.2 kps = 11, 200 m/s

    E= mc^2

    mv= mo/ sqrt (1- v^2/c^2)

    mv= mass of the object relative to stationary frame
    mo= proper mass
    v= velocity of the object

    3. The attempt at a solution
    No idea how to do this

    Percentage increase is ## \frac {m_v - m_0} {m_0} 100 \%##.
