    Acceleration Rod
AI Thread Summary
The discussion revolves around understanding the relationship between torque and angular acceleration in the context of a swinging rod problem. Participants are seeking guidance on how to approach the problem, emphasizing the need for hints to get started. The key concept highlighted is that torque is directly related to angular acceleration, as described by Newton's second law for rotation. Clarification on how to apply these principles to the specific problem is requested. Overall, the conversation focuses on foundational physics concepts necessary for solving the homework question.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
