The discussion centers on a physics-based quiz question regarding the dynamics of a seesaw mechanism involving stones labeled A, B, C, and D. Participants analyze the potential outcomes of a stone being pushed and its impact on the other stones. Key conclusions indicate that stone A is likely to be hit, while stones B and C are safe due to the mechanics of momentum and the configuration of the notch over stone D. The calculations of the circumference of the notched stone and the hypotenuse distance are suggested as critical components for understanding the scenario.
PREREQUISITESStudents of physics, educators teaching mechanics, and anyone interested in problem-solving within dynamic systems will benefit from this discussion.

swampwiz said:I think that if anything, A gets hit, but the stone could roll all the way through (besides, A could duck). I'm presuming that the notch fits perfectly over D, and there would be only horizontal momentum going to the seesaw, and with the other stone being heavier (i.e., no notch), it would not crush C, and would vault over the other stone (because of the kinetic energy), clearing B as well.
