Question

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.

Answer 1

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.
