Q. A toy train is pushed forward and released at x_0=2.0;{rm m} with a speed of 2.0 {rm m/s}. It rolls at a steady speed for 2.0 {rm s}, then one wheel begins to stick. The train comes to a stop 6.0 {rm m} from the point at which it was released. What is the magnitude of the train's acceleration after its wheel begins to stick?

Q. Suppose a block of mass 25.0 kg rests on a horizontal plane, and the coefficient of static friction between the surfaces is 0.220. what is the actual static frictional force that acts on the block if an external force of 25.0 N acts horizontally on the block?
