Calculate the mass of the moon if the free fall acceleration near its surface is known as 1.62 meter per second square and radius of the moon is 1738km.

  • Physics -

    F = m g = G m M/R^2
    so
    g = G M/R^2

    here G = 6.677 * 10^-11
    R = 1.738*10^6
    g is given = 1.62
    solve for M
