(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The problem is to find what 150lbs on earth = Xlbs on mars.

2. Relevant equations

F=G(m1)m2/d^2

G = 6.67x10^-11 (obviously)

3. The attempt at a solution

I'm getting incredibly annoyed because he gave us the wrong units etc, and we didn't even go over this in class. The last time I did this was in Highschool Physics...

150lbs = 68KG

mars has .108 the mass of Earth and the diameter is 6,787KM

FG (W) = 6.67x10^-11 (68 KG) 6.45x10^23 KG

___________________________ = 8.63 newtons?...

3393.5^2 KM

I know my answer needs to be 249N which = 56lbs (I went onto an online calculator thing)
