An elastic collision occurs between two pucks on an air-hockey table. Puck A has a mass of 0.025 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 0.060 kg and is initially at rest. The collision is not head-on. After the collision, the two pucks fly apart with the following angles:
Puck A is 65 degrees above the x axis
Puck B is 37 degrees below the x axis
a) Find the final speed of Puck A
b) Find the final speed of Puck B
