Lol. In an elastic collision , both Energy and Momentum are conserved. I was distracted 😅 .

Sin since there is no mention of conservation of energy in that equation , i'd say inelastic collision.

First i think the correct solution to the problem is But my friends argue that it is not what i did , i am confused we didn't see the whole chapter on momentum in class, (Youtube thank you) here is what my friends say : (0.3×5) + 0 = (V×0.3)+(0.4×2) and they get they a final speed of 2.33...

next time i will try to write everything in latex. Thanks for the help

it's make sense , thank you

We have studied one-sided limits. I don't know if i am getting you but from what i understand of your explanation "It should be clear that ##x \to \infty## only one formula is relevant." you meant that if x tends to +infinity i just need to study the formula defined in the interval [2...

I have troubles finding the limits at the designated points , should i only find the limit at infinity where f(x) has belongs to an interval containing inifinity? (sorry for english) and for the a this is what i attempted. i am unsure. Our textbook never talks about piecewise functions and...
