Elastic collisions in two dimensions: A billiard ball traveling at 3.00 m/s collides perfectly elastically with an identical billiard ball initially at rest on the level table. The initially moving billiard ball deflects 30.0° from its original direction. What is the speed of the initially stationary billiard ball after the collision?
A) 2.00 m/s
B) 0.866 m/s
C) 1.50 m/s
D) 2.59 m/s
E) 0.750 m/s
