Estimate the speed and direction of the first ball

Reference no: EM13673514

One billiard ball is shot east at 2.8 m/s. A second, identical billiard ball is shot west at 1.2 m/s. The balls have a glancing collision, not ahead-on collision, deflecting the second ball by 90 degree and sending it north at 1.42 m/s. Estimate the speed and direction of the first ball after the collision?
