## Homework Statement

Train starts to travel in a straight line at increasing speeds. The first wagon passes next to me in 4 seconds. In how many seconds will the n-th wagon pass next to me?

## Homework Equations

s= vo.t + 1/2at^2

v= vo + at

## The Attempt at a Solution

First of all we didn't learn sequences at school yet. That's why I try to solve it with these equations. Maybe the right question is "Is it solvable without knowing sequences?"

I tried to use the equation for velocity and compare then t1 with t2 with t3 and so on but there just so many unknowns and I can't figure anything out. Thank You I appreciate it.
