any other ideas?

Thanks for the idea, ideasrule (pardon the pun) :D Here it goes: d_1 - d_2 = 10m (1/2)(10m/s^2)(ts)^2 - (1/2)(10m/s^2)[(ts-1s)]^2 = 10m (5m/s^2)(t^2 s^2) - (5m/s^2)(t^2- 2t+ 1)(s^2) = 10m 5mt^2 - (5m)(t^2- 2t + 1) = 10m 5mt^2 - 5mt^2 + 10mt - 5m = 10m 10mt - 5m = 10m 10mt = 10m + 5m...
