Since force = mass X acceleration, then the force he excerts on the earth (aka his weight) equals his mass times the force of gravity.

Therefore
W = (66 kg) X (9.8 m/ss)
W = 646.8 kgm/ss

kg m/ss are also known as Newtons, so your answer is...

646.8 N

the man's weight on earth is 646.8 Newton.

Given the data in the question;

Mass of the man; [tex]m = 66kg[/tex]

The weight of a particle or object is the force of gravity on the object. its is expressed as:

[tex]W = m * g[/tex]

Where m is mass and g is acceleration due to gravity (on earth, [tex]g = 9.8m/s^2[/tex] )

We substitute the values into the equation

[tex]W = 66kg * 9.8m/s^2\\\\W = 646.8kg.m/s^2\\\\W = 646.8N[/tex]

Therefore, the man's weight on earth is 646.8 Newton.
