One billiard ball is shot east at 2.2 m/s. A second, identical billiard ball is shot west at 0.8 m/s. The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90 degree and sending it north at 1.54 m/s. Find the speed and direction of the first ball after the collision?
