(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A toy train is pushed forward and released at x_0 = 2.0 m with

a speed of 2.0 m/s. It rolls at a steady speed for 2.0 s, then one

wheel begins to stick. The train comes to a stop 6.0 m from the

point at which it was released. What is the magnitude of the

trainâ€™s acceleration after its wheel begins to stick?

2. Relevant equations

x_f = x_i +v*t +(1/2)*a*t^2

3. The attempt at a solution

O, well, I guess my attempt is this:

at x_0 = 2 m

v_0 = 2m/s

a_0 = 0 m/s^2

at x_1 = 6 m

v_1 = 2 m/s

a_0 = 0 m/s^2

and finally, through the relevant equation above,

8 = 6 + (2)(t) + (1/2)(a*t^2)

I have no idea how to complete this from here. Help?
