The planet mars has a mass of 6042e23 kg and a radius of 3038e6 m. how much would a 60 kg person weigh on Mars compared to their weight on Earth? How heavy he would feel he weighed in kg on Mars?

drwls,
The value of the acceleration of gravity "g" on Mars is
G*M/R^2
where the M and R are the mass and radius of Mars, which you have provided.
G is Newton's universal gravity constant.
Compare the Mars g to the g value on Earth, which is 9.8 m/s^2.
g is less on Mars. Weights on Mars will be reduced by the same factor.

Damon,
YOU MEAN:
6.042e23 kg and a radius of 3.038e6
Kg, mass, is the same everywhere.
weight in Newtons is m * local g
Fearth = m g = 9.81*60 = 588.6 Newtons = weight on earth
on Mars:
F = G 60 Mmars/Rmars^2
= 6.67*10^11 * 60 * 6.042*10^23/(3.038^2*10^12)
= 262*10^0 = 262 N = weight on Mars
