Question

titan is the largest moon of Saturn. if a 60 kg person stood on titan, they would have a weight of 81 N.
a. what is titan's mass if it has a radius of 2576 km?
b. what is the gravitational field strength of titan near its surface?​

Answer 1

Look up the value of G
F = GMm/r^2
So to find M, use GM*60/(2576*10^3)^2 = 81
g for Titan is GM/r^2

Answer 2

g Titan = m g / m = 81 N / 60 kg = (81/60) m/s^2
