Q. An automobile with an initial speed of 4.30m/s accelerates uniformly at the rate of 3 m/s/s. find the final speed and the displacement after 5 seconds.

Q. A toy train is pushed forward and released at x0 = 1.6m with a speed of 1.4 m/s. It rolls at a steady speed for 1.7 s and 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 train's acceleration after its wheel begins to stick?
