19 Mmoon: 0.0123ME
Rmoon: 0.272RE
MMars: 0.107ME
RMars: 0.530RE
Above, the masses and radii of the moon and Mars are given as fractions of the mass and
radius of the earth. Calculate their accelerations due to gravity at their surfaces. [Below,
the masses and radii of the moon and Mars are given as fractions of the mass and radius
of the earth. Calculate their accelerations due to gravity at their surfaces. [The
calculation is simplified if you directly substitute in the equation the lunar and Martian
fractional factors for mass over radius squared and multiply the answers times 9.8.]
