OK thank you ! Last question before we end this : Why do you think I blocked on this particular point ? Why would this happen ? Lack of knowledge in physics ? I guess this is my best bet... Also, did I bother you?gneill said:
We all come across concepts that, for whatever reason, seem to be counter intuitive at first and take some time and brain sweat to resolve. Once the "Aha!" moment occurs and you get it it's usually smooth sailing from there with a bit of practice. Learning to write energy conservation equations for different situations in order to uncover some particular parameter is one of those things that requires a bit of practice.astrololo said:
I volunteer my time because I enjoy helping students. Students who persevere and continue to make an effort when things get tricky are never a problem.To be honest, I didn't get the "Aha" moment because I just assumed that what you said is true. I mean, I did think of the possibility that the middle would be the "0" but I wasn't 100 % sure because there was no indication that this would be the case. In any case, the problems given are simple and of this type that I just did. I need to learn more physics in my free time. It's good to know there are people who are here to help others.

And no, you didn't bother me
