The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.036 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 0.056 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. m/s (b) Find the final speed of puck B. m/s
