On earth, 1 kg = 9.8 n = 2.2 lbs. on the moon, 1 kg = 1.6 n = 0.37 lbs. use these relationships to answer the following questions. show your work. a. what is weight, in newtons, of a 50.-kg person on earth? b. what is the weight, in newtons, of a 50.-kg person on the moon? c. what is the mass, in kilograms, of a 100.-lb. person on earth? d. what is the mass of the person in question c on the moon?

(a) 490 N on earth

(b) 80 N on earth

(c) 45.4545 kg on earth

(d) 270.27 kg on moon

Explanation:

We have given 1 kg = 9.8 N = 2.2 lbs on earth

And 1 kg = 1.6 N = 0.37 lbs on moon

(a) We have given mass of the person m = 50 kg

As it is given that 1 kg = 9.8 N

So 50 kg = 50×9.8 =490 N

(b) Mass of the person on moon = 50 kg

As it is given that on moon 1 kg = 1.6 N

So 50 kg = 50×1.6 = 80 N

(c) We have given that weight of the person on the earth = 100 lbs

As it is given that 1 kg = 2.2 lbs on earth

So 100 lbs = 45.4545 kg

(d) We have given weight of the person on moon = 100 lbs

As it is given that 1 kg = 0.37 lbs

So 100 lbs
