  • Another Physics Question?

    A cue ball of mass 0.17 kg hits a nine ball with mass 0.16 kg that is initially at rest. If the nine ball is cut in such a way that both balls leave the impact with a 25 degree angle, what are their velocities after impact? Assume the cue ball has an initial velocity of 15 m/s.
