| Jul 14, 2021 at 14:01 | comment | added | fishinear | @rayan Free body diagrams of the system just before a move, and just after a move seems most applicable. Conservation of energy is not going to help you, because the friction is converting kinetic energy into thermal energy. | |
| Jul 14, 2021 at 13:58 | comment | added | fishinear | @rayan Before the loading you start with a block with no horizontal forces on it (I assume), and after the unloading, there is a spring force balanced by the frictional force. So yes, it will not return to the starting point after unloading. | |
| Jul 14, 2021 at 13:51 | comment | added | rayan | Thank you very much for the detailed response. So if I understand correctly, the distance traveled by the block during the unloading cycle (when weights are removed) would always be less than the distance traveled during the loading cycle (when weights are added). On a side note, should I try to tackle the problem by having force equilibrium, a free body diagram of the system at the initial and final position or by doing conservation of energy to determine the travel 'x' of the block? | |
