A particle of mass m1 = 2.5 kg moving along the x axis collides with a particle of mass m2 = 4.7 kg initially at rest. The incoming particle is deflected in the direction 24 degrees above the x axis, whereas the target particle moves off at 14 m/s at 39 degrees below the x axis. What are the initial and final speeds of the 2.5 kg particle?
