The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.0350 kg and is moving along the x-axis with a velocity of +6.45 m/s. It makes a collision with puck B, which has a mass of 0.0700 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the angles shown in the drawing. Find the speed of (a)puck A and (b) puck B.
