OK, but you said in your first message that we're finding 'a' "while exhibiting a constant retardation", hence there's a single solution for 'a'... shirley? If you want me to go from 20m/s to 0 in 10 seconds using constant retardation, then I'll do it over 100m. If you only want me to go 50m, then I have to come to a halt within 5 seconds. What you can't do is ask me to take 10 seconds but only travel 50m. Mike
