Centripetal or centrifugal?

  • #1

Homework Statement



13. Why does the water in a washing machine escape through the little holes during the spin cycle?
a The water is flung out of the clothes by the centripetal force.
b The water is flung out of the washer by the centrifugal force.
c The water is sucked out of the little holes by the washer.
d The washer cannot force the water into a circle because of the holes.



Homework Equations



I believe it's either a or b.

The Attempt at a Solution


I can't narrow it down between the tow. Help is very appreciated!

BTW don't let anyone tell you that the term 'centrifugal force' is wrong. Richard Feynman used it in his (recently posted) lecture series, and he kind of knew his physics. :smile:

Shouldn't the answer be "d"? If the outer tub is draining, then the holes on the inner tub above the outer tub water line can't produce a centripetal force on the water, and the water's momentum causes it to flow through the holes into the outer tub.

That's my vote too, for what it's worth.
