Answer:
646.8
Weight in Newtons can be found by multiplying the mass times the acceleration of gravity.
The mass of the man is 66 kilograms on Earth.
Earth has an acceleration of gravity that is 9.8 meters per square second.
Substitute the values into the formula.
Multiply.
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.
The man's weight in Newtons in 646.8 Newtons
