One billiard ball is shot at 2.19 m/s at east. The second, alike billiard ball is shot at 1.04 m/s at west. The balls encompass a glancing collision, not a head-on collision, deflecting the second ball by 90 degree and sending it north at 1.42 m/s. Find out the speed of the first ball after the collision?
Determine the direction of the first ball after the collision? Present the direction as an angle (in degrees) south of east.
