Q. A toy train is pushed forward and released at x_0 = 4.0 m with a speed of 1.0 m/s. It rolls at a steady speed for 2.0 s, then one wheel begins to stick. The train comes to a stop 4.5 m from the point at which it was released.
Q. A car drives north at 42 mi/h for 10 min and then turns east and goes 5.0 mi at 62 mi/h. Finally, it goes southwest at 30 mi/h for 6.0 min.
(A) Determine the car's displacement. (dx,dy)
(B) Determine its average velocity for this trip.
