An object weighs 1247 n on earth's surface. the acceleration due to gravity on the moon is 1.62 m/s2. what is the object's weight on the moon? 200 n 206 n 177 n 189 n

The answer will be 206 N

reasoning:

you must recognize that the problem gave you the force due to weight on earth, which similarly on the moon will be F = mg, just a restatement of Newton’s Second Law.

so given the 1247 N on earth:

1247 = mg
1247 = m(9.8 m/s^2)

1247
—— = 127 kg for the mass
9.8

Now implement this equation with the known mass for moon’s gravity

F = (127kg)(1.62m/s^2)

F = 205.74 N or 206 N

Hope this helped!! Thank you for posting your question.

2. they have negligible mass.
