Answer! do you think it is easier or harder to hammer a nail into a floorboard on pluto than on earth? how about the sun? explain.

Harder On Pluto

Explanation:

Although the mass of the hammer and the acceleration your hand gives it during the nailing process might be equal and therefore the force exerted on the nail might be the same as on earth, but the gravity on Pluto is much smaller than on Earth, although minor in magnitude, less gravitanional force on the nail on Pluto, might require a little more force to drive the nail

the answer is b, have negligible mass
