The drawing shows a collision between two pucks on an air-hockeytable. Puck A has a mass of 0.0190 kg and is moving along the xaxis with a velocity of +4.63 m/s. It makes a collision with puckB, which has a mass of 0.0380 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks flyapart with the angles shown in the drawing. Find the speed of (a)puck A and (b) puck B.
