Question

*A red ball with a velocity of +3.0 m/s collides head-on with a yellow ball of equal mass moving with a velocity of ?2.0 m/s. What is the velocity of the two balls after the elastic collision?
A red ball with a velocity of +3.0 m/s collides head-on with a yellow ball of equal mass moving with a velocity of ?2.0 m/s. What is the velocity of the two balls after the elastic collision?
-The velocity of the red ball is ?2.0 m/s; the velocity of the yellow ball is +3.0 m/s.
-The velocity of the red ball is +2.0 m/s; the velocity of the yellow ball is ?3.0 m/s.
-The red ball stops immediately, and the yellow ball has a velocity of +1 m/s.
-The velocity of the red ball is ?3.0 m/s; the velocity of the yellow ball is +2.0 m/s.
-The yellow ball stops immediately, and the red ball has a velocity of ?1 m/s.
-The velocity of the red ball is +3.0 m/s; the velocity of the yellow ball is ?2.0 m/s.

Explanation / Answer

The velocity of the red ball is 2.0 m/s; the velocity of the yellow ball is +3.0 m/s.
