Two identical pucks are set on a collision course on an air table both with an angle of 36 degrees from the vertical.

Two identical pucks are set on a collision course on an air table both with an angle of 36 degrees from the vertical. After the collision, Puck A has a final velocity of 5 cm/s at an angle of 28 degrees from the vertical and puck B has a final velocity of 4 cm/s at an angle of 32 degrees from the vertical. Determine the initial speeds of both pucks.
