What percent of Earth's acceleration due to gravity is the acceleration on Mars? Take G = 6.67 x 10^-11 N m^2/kg^2 and the
mass of Mars 6.42 x 10^23 kg and its radius as 3400 km. (Answer should look like '55.5 %'.)
At what altitude above Earth's surface would the gravitational acceleration be 3.80 m/s2? (Take the Earth's radius as 6370 km.)
The acceleration of gravity upon Mars' surface is 3.75 m/s/s. At a location of 'R' above Mars' surface (otherwise known as
2R), the acceleration of gravity is closest to ________ m/s/s.
