What is the acceleration of gravity on Mars if a person with a mass of 60.0 kg weight 222 N on Mars?

The mass (m) is given as 60kg and the force (f ) is the gravitational force acting on a body of such mass (this equates to the weight). We use" f = ma", where a is the acceleration.

So the answer is: a = f/m = 222/60 = 3.7 (meters per second squared).
