The correct answer is D. The red ball begins moving along the x-axis at a speed of -5, and the blue ball begins moving. See the full explanation below for the reasoning.
Question
You are programming a game that perfectly features elastic collision. A red ball is traveling along the x-axis with a speed of +5 and a blue ball is traveling along the x- axis with a speed of -5. There is no motion on any other axis. Each ball has identical mass. They collide with the center of each ball perfectly aligned with the other. What reaction motion should you expect after the collision?
Options
- ABoth balls begin moving along the y-axis at a speed of -S.
- BBoth balls stop, and there is no more motion.
- CThe red ball stops, and the blue ball begins moving at a speed of +10 along the x-axis.
- DThe red ball begins moving along the x-axis at a speed of -5, and the blue ball begins moving
