comment Velocity at which the second locomotive will catch the first without passing it?
I set s1 and s2 equal to each other, I get 1.4t^2=v(t-10). Then I get v = 1.4t^2/(t-10). Plugging that back into s2 you get the same answer as s1. What am I doing wrong?

can you please explain how you got (t-10) ? shouldn't it be t+10, since train number 2 is starting 10 seconds later?
