A particle with an initial linear momentum of 4.80 kgm/s directed along the positive x-axiscollides with a second particle, which has an initial linearmomentum of 9.60 kg · m/s, directedalong the positive y-axis. The final momentum of the firstparticle is 7.20 kg · m/s, directed45.0° above the positive x-axis. Find the finalmomentum of the second particle.
