A puck of radius 2R approaches two smaller pucks of radius R at 0.4 m/s along a line between them as shown. It strikes them simultaneously pushing them away at the same angle above and below the original puck direction. The collision causes the large puck to slow to 0.2 m/s. The pucks all have the same thickness and density.   (a) What is the x-component of the velocity of the smaller pucks
