A toy train is pushed forward and released at = 3.5 with a speed of 1.0 . It rolls at a steady speed for 1.2 , then one wheel begins to stick. The train comes to a stop 3.4 from the point at which it was released.What is the train's acceleration after its wheel begins to stick?

without units, none of this makes sense.

A toy train is pushed forward and released at = 3.5 m with a speed of 1.0m/s . It rolls at a steady speed for 1.2s , then one wheel begins to stick. The train comes to a stop 3.4m from the point at which it was released.What is the train's acceleration after its wheel begins to stick?

stopping distance=3.4-1.2=2.2m

Vf^2=Vi^2+2ad solve for a, knowing Vf=0, Vi=1m/s, d=2.2m
