The drawing shows a collision between two pucks on an air-hockey table. Puck A has a mass of 0.28 kg and is moving along the x axis with a velocity of 5.80 m/s. It makes a collision with puck B, which has a mass of 0.56 kg and is initially at rest. After the collision, the two pucks fly apart with angles as shown in the drawing (α = 56° and β = 40°). Find the final speed of puck A. I tried 4.83m/s and 1.719m/s and both were incorrect. pls help.
