Answer:


\boxed {\boxed {\sf 646.8 \ Newtons }}

Step-by-step explanation:

Weight in Newtons can be found by multiplying the mass times the acceleration of gravity.


W=m*g

The mass of the man is 66 kilograms on Earth.

Earth has an acceleration of gravity that is 9.8 meters per square second.


m= 66 \ kg \\g=9.8 \ m/s^2

Substitute the values into the formula.


W=66 \ kg *9.8 \ m/s^2

Multiply.


W=646.8 \ kg*m/s^2

1 kg * m/s² is equal to 1 Newton, therefore our answer of 646.8 kg *m/s² is also equal to 646.8 Newtons, or N.


W=646.8 \ N

The man's weight in Newtons in 646.8 Newtons.
