A cue ball traveling at 3.81 m/s makes a glancing, elasticcollision with a target ball of equal mass that is initially atrest. The cue ball is deflected so that it makes an angle of 30.0°with its original direction of travel.
(a) Find the angle between the velocity vectors of the two ballsafter the collision.
  ______°
(b) Find the speed of each ball after the collision.
| cue ball    | ____m/s |
| target ball    | ____ m/s |
