If a man weighs 155 lb on earth, specify (a) his mass in slugs, (b) his mass in kilograms, and (c) his weight in newtons. If the man is on the moon, where the acceleration due to gravity is determine (d) his weight in pounds, and (e) his mass in kilograms

a) 4.81 slug

b) 70.30 kg

c) 689.47 N

d) 25.73 lb on the moon

e) 70.30 kg

Explanation:

Given that

Weight, wt = 155 lb

We know that

1 slugs = 32.174 lb

1 lb = 0.031 slug

m = 4.81 slug

1 lb = 0.453 kg

155 lb = 70.30 kg

1 lb = 4.448 N

155 lb = 689.47 N

Weight on the earth = 0.16 x moon on the moon

155 lb on the earth = 25.73 lb on the moon

We know that mass does not depends on the gravity constant g that is why the mass on the moon will be same as the mass on the earth that is 70.30 kg.

a) 4.81 slug

b) 70.30 kg

c) 689.47 N

d) 25.73 lb on the moon

e) 70.30 kg
