    2 dimensional collision confusion

    Homework Statement A 2 kg mass with initial velocity v = (5i + 7j) collides perfectly elastically with a 3 kg mass with initial velocity v = (-1i -3j) After the collision, the 2kg mass has a speed of √50 m/s and the 3 kg mass is traveling at an angle of 329.77Θ as measured from the...
