(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A certain nucleus at rest suddenly decays into three particles, two of which are charged and can be easily detected. The data gathered for these two particles is:

- Particle 1 has mass 2.93e-25 kg moving 5.69e+06 m/s at 69.5o.

- Particle 2 has mass 1.33e-25 kg moving 9.31e+06 at 221o.

Find the Momentum of the third particle

_____i km m/s + _____ j km m/s

3. The attempt at a solution

I tried first calculating the Momentum of each of the particles and then split the 2D momentum vectors into i and j

and then i set that the sum of all the i's = 0 and that the sum of all the j's = 0 since there aren't any external forces and momentum is conserved and then i tried solving for the missing i and the missing j.

I keep getting the answer wrong...

Thanks for your help
