I can't get seem to be the right answer

A firework explodes into three pieces as shown in the diagram below. Now that you have set up the equation for the a and y components of the final momentum of the firework, let's do some physics! Given: . The initial firework had a mass of 9:0 kg and was launched at vi = 80 m/s vertically straight up . The firework explodes into three pieces of equal mass 3.0 kg. The angles 01 =03 = 30 . Speed v] = 100 m/s. What is the speed v2? Note: the angles shown for mass mi and mass my are relative to the horizontal x axis. Mass m2 is moving straight up (y axis). m2
