A man has a mass of 66 kg on the earth. What is his weight.
145.5 pounds hope this helps
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
