The Law Posted March 28, 2010 Report Share Posted March 28, 2010 Can someone please help me work through this? The way I solved it was saying: d= Vot + 1/2(a)(t^2) t in the question refers to the total time of the trip. Since the trip up and down is the same amount of time, whatever happens to half the trip will also happen to the full thing. I then said, Vo = 0, because at the top of the flight you would have no velocity. This lead me to saying: d = (1/2)(a)(t^2) Which can be rearranged to: sq root (2d/a) = t Now suppose a = g/6 as suggested in the question, then the factor that t is changing by is sq root 6. This was no the right answer. I don't know what I did wrong. This is a pretty simple problem, so I'm hoping I don't get something like this wrong again! Any help would be super appreciated. I don't understand how they got to t = 2v/g, and why my method failed. Link to comment Share on other sites More sharing options...
