The person weighs 8.14N in mars.
The complete question is the following:
A physical science text book has a mass of 2.2 kg. What is the weight on mars (g =3.7 m/s2) of the book?
________________________________
The Newton's second law states:
If a net external force acts on a body, the body accelerates. The direction of acceleration is the same as the direction of the net force. The mass of the body times the acceleration vector of the body equals the net force vector.
In a mathematical language:
[tex]\Sigma \vec{F}=m\vec{a} \\ \\ \vec{F}:Force \\ \\ m:mass \ of \ the \body \\ \\ \vec{a}:Acceleration[/tex]
In this exercise, we have that a physical science text book has a mass of 2.2 kg, so wight is a force and the acceleration due to gravity in mars is:
[tex]g =3.7 \frac{m}{s^2}[/tex]
So the magnitude on mars of the weight (w) of this book is given by:
[tex]w=mg \\ \\ w=2.2\times 3.7 \\ \\ \boxed{w=8.14N}[/tex]
