A Stone connected to chain is thrown vertically

Click For Summary
SUMMARY

The discussion centers on the dynamics of a stone connected to a chain thrown vertically, analyzing the forces and equations of motion involved. Key equations derived include Newton's second law for the stone, $$-F-mg=m \ddot h$$, and the impulse-momentum relationship $$\frac{dp}{dt} = F - \lambda gh$$. Participants debate the conservation of work and momentum, highlighting the complexities of chain dynamics and the potential loss of energy during motion. The final consensus suggests that the maximum height of the stone is influenced by both the initial speed and the length of the chain, with calculations indicating a maximum height of 40 m under specific conditions.
