If a man weight 155 lb on earth, specify
(
a. his mass in slugs,
(
b. his mass in kilograms, and
(
c. his weight in newton’s. if the man is on the moon, where the acceleration due to gravity is gm = 5.30 ft/s2, determine
(
d. his weight in pounds, and
(
e. his mass in kilograms.

For the answer to the question above, on Earth, a one-pound object has a mass of about 0.453592 kilograms. 

Therefore the man's mass is 155 * 0.453592 = 70.30676 kilograms. 

The part about the Moon's gravity is irrelevant. While the weight of a person or object would be different on the Moon, the mass would be the same.
