The drawing shows a collision between two puckson an air-hockey table. Puck A has a mass of 0.0190 kg and ismoving along the x axis with a velocity of +4.63 m/s. It makes acollision with puck B, which has a mass of 0.0380 kg and isinitially at rest. The collision is not head-on. After thecollision, the two pucks fly apart with the angles shown in thedrawing. Find the speed of (a) puck A and (b) puck B.
