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.
