Question

If a person weighs 750 n on earth,how much would be his weight on the moon given that moon's mass is 1/81 of that of the earth and it's radius is 1/3.7 of that of the earth

Answer 1

Answer:the weight will be one sixth of that measured in earth, therefore it will be 125n

Explanation:

Answer 2

Answer:

Explanation:

F = 750 N

m1 = 1 man mass unit

m2 = 81 astronomical body mass units

r = 3.7 astronomical body length units

and solve for “G” in the arbitrary units adopted for this problem.

Now use Newton’s equation again to calculate F. On the moon:

m1 is still 1 man mass unit

m2 is now 1 astronomical body mass unit

r is now 1 astronomical body length unit

You answer should be close to (but not exactly) 125 N.
