The mass of mars is 6.42 x 10^23 kg and its radius is 3.38 x 10^6m, What is the weight of a 70.0 kg student on this planet?
I know weight equals (m)(a) but im not sure how to relate it to the information given

Forceg=GMm/r^2 M mass of Mars, m mass of student, r=distance apart, or the radius of the Planet.

w=mass* surface gravity w=154*0.38=58.5
