# Which of the following is true(about the case below)? Case: A 0.2 kg red cue ball rolling at 1.4 m/s elastically collides directly with a 0.2 kg 9-Ball at rest.

A. The 9-ball would have a velocity greater than 2 m/s
B. The 9-ball would have a velocity greater than 0.5 m/s but less than 2m/s
C. The red cue ball would have a velocity greater than 1.0 m/s
D. The red cue ball would have a velocity of 0 m/s
E. The two cue balls would stick together and have the same velocity

One way to make complex math problems easier to understand is to relate them to everyday things. This can make the process of solving math problems more fun as well as more understandable. The mathematical explanation of impulse and momentum can be explained with the help of a scenario involving balls used to play pool.

If a 0.2 kilogram red cue ball rolling at 1.4 m/s elastically collides directly with a 0.2 kilogram 9 ball at rest the red cue ball can be expected to have a velocity of 0 m/s. Visualizing the balls helps make the problem much easier to understand.    #### John Smith
