The discussion revolves around a collisions problem, specifically addressing the final velocities of two masses involved in a collision. Participants are examining the conditions under which these velocities might be equal, particularly in the context of elastic versus inelastic collisions.
There is an active exploration of the conditions under which the final velocities of the masses might be equal. Some participants express agreement with the questioning of the original problem's assumptions, indicating a productive dialogue about the nature of the collision.
Participants note that the original problem does not specify whether the collision is elastic or inelastic, which is central to their discussion. There is also a mention of the behavior of the masses post-collision, which further complicates the assumptions being made.
I agree.toesockshoe said:how do you know that the final velocities of both masses are equal to each other? wouldn't that ONLY be hte case if the collision was perfectly inelastic (which he didnt mention).
alright, and in this case it would be simply impossible for the masses to have the same velocity... because the first mass (the mass on the left) would move left after the collision correct?haruspex said:I agree.
nevermind scratch that... that would only happen if it is an elastic collision... this may or may not happen in an inelastic collisiontoesockshoe said:alright, and in this case it would be simply impossible for the masses to have the same velocity... because the first mass (the mass on the left) would move left after the collision correct?
