AI Thread Summary
The discussion centers on the interpretation of the phrase "slammed into" in the context of a comet or asteroid colliding with Earth. Participants debate whether this implies the celestial body combined with Earth after the impact or if it could have other outcomes, such as bouncing off. The term "prompt" refers to the initial statement or question that guides the discussion. There is an emphasis on making assumptions about the motion of the comet or asteroid post-collision. Overall, clarity on the implications of the phrase is sought for better understanding of the event's dynamics.

What does "slam into" mean?

The prompt about impulse and momentum says "a large comet or asteroid slammed into the earth". Does the prompt means that the comet or asteroid combined with the Earth after collision and moved together at same speed after the collision?

What's a 'prompt' in this context?
 


I asked prof and he said I should make an assumption about the motion after collision. Thank you DaveC426913.
 


I think the phrase "slammed into" could equally well be followed by any number of phrases such as, for example, (1) "and was absorbed by", (2) "and bounced off off"
 


@phinds
Yes exactly! So I was asked to make assumptions.

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 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
