Question 25 (9 points) During a game of billiards, Danielle shoots the 0.30-kg cue ball, $m_1$, at 2.1 m/s. It glances off a stationary 0.28-kg billiard ball, $m_2$, so that the billiard ball moves off at $v_{2y} = 1.1$ m/s [N] and $v_{2x} = 0.86$ m/s [E] from the cue ball's original path. Find the new velocity of the cue ball. (9 - marks).
