1. The problem statement, all variables and given/known data

An object with total mass mtotal = 16.6 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.9 kg moves up and to the left at an angle of θ1 = 18° above the –x axis with a speed of v1 = 25.5 m/s. A second piece with mass m2 = 5.5 kg moves down and to the right an angle of θ2 = 23° to the right of the -y axis at a speed of v2 = 23.9 m/s.

What is the x-component of the velocity of the third piece

2. Relevant equations

I know the final P=0 and the mass of the third object = 6.2kg

3. The attempt at a solution

I tried finding the x component for m2 which I got to be 10.144 by tan(23)*23.9, and we know the x component of m1, so I multiplied these x components by their masses and added them, since P=0 I then subtracted them to the other side of the = sign to give me the opposite. I dont know if I am on the right track or not. I have tried every way I can think of to do this problem, cant get the right answer.
