An astronaut has a mass of 100 kg and has a weight of 370 N on Mars. What is the gravitational strength on Mars?

##g=3.7N##/##kg##
The weight(##w##) of an object with mass (##m##) in a gravitational field with strength(##g##) are related by the formula:
##w=mg##
##=>g=w/m##
In our case:
##=>g=(370N)/(100kg)##
##=>g=3.7N##/##kg##
