Elastic Collisions in Two Dimensions: a Billiard Ball Traveling at 3.00

question 34

Multiple Choice

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.

• 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
