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 train’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?
