Two pucks collide on an air hockey table. Puck A has a mass of 30 g and is initially traveling in the +x direction at 6.0 m/s. Puck B has a mass of 120 g and is initially at rest. After the pucks collide, puck A moves away at an angle of 52above the +x axis, while puck B travels at an angle of 20 below the +x axis.
Calculate puck A's final speed.
