| Oct 12, 2015 at 11:41 | comment | added | Daniel Griscom | @1110101001 As for the weights falling off, that depends on a number of things you never specified in your question. | |
| Oct 12, 2015 at 11:41 | comment | added | Daniel Griscom | @1110101001 The relative weights matter, but there's no marked change in behavior between the hanging weight being smaller than the resting weight and the hanging weight being larger. (Why would there be?) | |
| Oct 12, 2015 at 3:23 | comment | added | 1110101001 | @DanielGriscom Sorry to bump an old question, but why would it not matter if the hanging weight is smaller than the resting weight? I'm guessing because the tension is still present in both cases, and this would propel the cart. Doesn't this mean the cart would remain moving perpetually though, since the weights would never fall off? | |

| Oct 3, 2015 at 20:28 | comment | added | dmckee --- ex-moderator kitten | Well, it doesn't change the answer to "Does it move?", but it does change the answer to "How far has it gone before the falling block hits the ground? And how fast is it moving at that time?" because the falling block is no longer constrained to have the same horizontal velocity as the cart. | |

| Oct 3, 2015 at 11:45 | comment | added | Daniel Griscom | For this question, it doesn't matter that the hanging weight is larger than the resting weight. The result (excepting its magnitude) will be the same. | |
