AI Thread Summary
The discussion centers on the point at which a swing rider feels the lightest, with a consensus leaning towards the upward motion of the swing. It is suggested that the upward velocity counteracts gravity, effectively reducing the rider's perceived weight. The conversation also touches on the forces acting on the rider at a general angle, highlighting the tangential and centripetal components. Understanding these forces is crucial for determining the resultant normal force. Ultimately, the interplay of these forces defines the sensation of weightlessness experienced by the swing rider.

At which point does the person on the swing feel the lightest?

I'm leaning towards #2 and I'm pretty sure it's #2, but I just need to make sure. I'm not sure if this is correct or not, but I believe the velocity acting on the person (upwards), cancels out the gravity or lowering the effects of gravity, thus weight would be lower [w=m(g)].

At a general angle θ, what would the components of the force? (one is tangential while the other points toward the center of rotation)

When you get that, remember that the resultant of the normal force and the component provide the centripetal force FC

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}...
