The drawing shows a collison between two pucks on an air-hockey table.Puck A has a mass of 0.032 kg and is moving along the x axis with a velocity of +5.5 m/s.It makes a collision with puck B, which has a mass of 0.052 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.

a) Find the final speed of puck A.

b) Find the final speed of puck B.
