Homework Statement
The problem is to find what 150lbs on Earth = Xlbs on mars.
Homework Equations
F=G(m1)m2/d^2
G = 6.67x10^-11 (obviously)
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 KMI know my answer needs to be 249N which = 56lbs (I went onto an online calculator thing)
