One billiard ball is shot east at 2.4 m/s. A second, identical billiard ball is shot west at 1.2 m/s. The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90° and sending it north at 1.42 m/s. ▼ Part A What is the speed of the first ball after the collision? Express your answer to two significant figures and include the appropriate units. V= Submit ▾ Part B HÅ Value Request Answer SAC Units ? What is the direction of the first ball after the collision? Give the direction as an angle sou Express your answer to two significant figures and include the appropriate units.
