    By Newton's Law of Gravitation,

    a = GM / r²

    where G = 6.674e−11 N·m²/kg²

    and M is the moon's mass

    and r is the moon's radius

    a = 6.674e−11N·m²/kg² * 7.35e22kg / (1.74e6m)²

    a = 1.62 m/s²

    Hope this helps!

    By g' = GM/R^2

    =>g' = [6.67 x 10^-11 x 7.35 x 10^22]/(1.74 x 10^6)^2

    =>g' = 1.62 m/s^2
