    So I'm near the end of a problem wherein two masses of identical size and shape are dropped from the same height and I have to find the difference in the time they take to reach the ground. At first I thought it was the same because I used an approach whereby (I hope you can follow my working!):

    I end up with an identical time for both masses, to first order k/m. However I think there may be more to it than that... does the lamda*mass term change things for the heavier mass? Or is my working correct? If you can give any other advice or feedback, please do so. I have been stumped on this problem for days now and need to hand it in.

    Also, is it true to say that
    k/m. ((SQRT(2h/g)^3)/6 is the same expression as hk/3mg? Again I hope you can follow my working. If anyone has trouble and happens to use the Mathtype software, I can upload the working in that format to make it easier for them to read.
