Collision Conservation of momentum

AI Thread Summary
In an inelastic collision between two objects moving towards each other, the instantaneous velocity at the point of collision is zero if their masses and velocities are equal. The outcome depends on the specific masses and velocities of the objects involved. The discussion highlights the importance of impulse, which relates to the change in momentum during the collision. Analyzing the impulses allows for the calculation of forces and accelerations, leading to a better understanding of the speeds at various points in the collision. Overall, the instantaneous velocities of both objects can be determined by considering their initial conditions and the principles of momentum conservation.

Homework Statement


If two objects one traveling right and the other traveling left collide. The collision is inelastic.
What would the sign of the instantaneous velocity of each object?


Homework Equations





The Attempt at a Solution


I think the instaneous velocity would be zero for both the objects at the point of collision but iam not sure.

It depends on the velocity of the objects and their masses. If both m's and v's are equal, then it would stop.

You may be talking about the act of them combining, where you would have to look at the impulses of them both. Impulse=Ft=change in momentum. From there, you can find force, acceleration, etc. and find the speeds at certain points in the collision, I believe.

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}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
