But aren't the horizontal velocities different between the two scenarios?
Missed that part of the question, sorry. From the math in the initial post though, I have a question...is the height identical both times? If so, the time works out as above, and it turns into
d1 = 2v2*t1
d2 = v2*t2 = v2*t1*sqrt(2) = 0.5d1*sqrt(2)
sqrt(2)/2 = 2/2sqrt(2) = 1/sqrt(2)
so, yeah, if the heights are the same, it should be D. But at this point, I'm not certain that the problem is complete as posted...there have been bits and pieces left out throughout, and of course, if OP is getting it wrong, the odds are they are overlooking a crucial bit of info (the most common reason to miss problems), so
only providing what seems pertinent is kind of defeating the purpose of having another set of eyes on it.
Honestly, this whole thing would be easier if people would post the ENTIRE problem in the initial post. It's far harder to piece it together from 2 posts, neither of which has the whole story. People help out on these things as a favor, it is only hurting your chances of getting a good response if you do not make it easy on us by providing all of the info needed.
