If a man weighs 155 lb on earth specify a his mass in slugs

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 g_m = 5.30 ft/s^2, determine (d) his weight in pounds, and (e) his mass in kilograms.

Solution

Answer to the question)

1 lb = 0.03108 Slugs

Thus 155 lb = 155 * 0.03108 slugs

155 lb = 4.8174 Slugs

.

1 Lb = 0.45359 kg

155 lb = 155 *0.45359 kg

155 lb = 70.30645 kgs

.

I lb = 4.45 Newton

155 lb = 155 *4.45 Newtons

155 lb = 689.75 Newtons
