Oh okay, thank you, now I get the correct answer for c, but b is still not working out, could you please help me with that?
please, I honestly keep trying to look at the problem from different points of view, but nothing is working out; I'm running out of ideas as to how I can approach and still, I'm not getting the right answer or understanding drwls' answers...
Please, I've been trying to solve this problem for hours and I still can't get the correct answer, I would really appreciate some more help with this.
Won't the kinetic energies for question b and c be the same?
Also, is there a final kinetic energy? I'm just really confused by this...
Oh, and what do you mean by 'x'?
Should the answer for B be 1.5x10^6 m/s because my book says it's wrong...
Please, please, please, this is the first question of many and I don't get it.
thank you! :)
Which tense are you supposed to be using?
oh okay, thank you very much. :)
Also, I think I've found the first velocity, but would I disregard that when finding the velocity at point B?
I tried doing that; can you please explain. Wait, so, would the first velocity be mgh=1/2mv^2 and then I take away the m's?
