    In the mark scheme they use 30 for t and 1.5 for V0 , Why dont they use 40 for t and 1.0 for v0?

    My impression is that you can use any correct values.

    I guess if we start talking about errors and stuff (though, as t increases V decreases so.. :dontknow:) I think you'd be pretty close anyway.

    True they can be confusing sometimes. Yeah.. pick anything that has a nice t value and a nice V value. Using 20 gives 21.8 which is pretty darn close and acceptable (from the 22+/-1).
