Question

A bag of sugar weighs 4.00 lb on Earth. What would It weigh in newtons on the Moon, where the free-fall acceleration is one-sixth that on Earth? Repeat for Jupiter, where is 2.64 times that on Earth Find the mass of the bag of sugar in kilograms at each of the three locations Earth Moon ter Need Help? Wat

Answer 1

Answer 2

SOLUTION :

Weight on moon of a 4 lb bag on earth in Newtons 

= m g / 6  

(where mass m is in kg on earth and g is free fall acceleration in m/s^2 on earth))

= 4 / 2.20462 * 9.8 / 6

= 2.96 N (ANSWER)

Weight on Jupiter of a 4 lb bag on earth in Newtons 

= m g(jupiter)  

(where mass m is in kg on earth and g(Jupiter)is free fall acceleration in m/s^2 on Jupiter))

= 4 / 2.20462 * 2.64*9.8

= 46.94 N (ANSWER)

Mass of bag  :

Mass remains same anywhere.

So, 

Mass on Earth   :  4/2.20462    = 1.8144 kg

Mass on Moon  : 1.8144 kg

Mass on Jupiter : 1.8144 kg 

(ANSWER).
