Homework Statement
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?
Homework Equations
x_f = x_i +v*t +(1/2)*a*t^2
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?
