3. Toy Train: A toy train pushed forward and released at x0=2.0 m with a speed of 2 m/s. It rolls at a steady speed for 2 s, then one wheel begins to stick. The train comes to a stop at 6m from the point at which it was released. What is the magnitude of the train's acceleration after its wheel begins to stick?

1. Consider an object on some trajectory r(t) and define v = r' as the velocity with speed v = [r'|. (a) Show that we can write v = vT. (b) Show that we can write the acceleration as a = arT + anN where ar and an are the tangential and normal acceleration components that are func- tions of the speed and curvature. Explain why an object with constant speed can still experience an acceleration. (c) Consider a trajectory r(t) = (t² – 1,t – t³). Compute the curvature as well as the tangential and normal components of the acceleration.
