Question

A 0.200-kilogram ball A is traveling at a velocity of 2 meters/second. It hits a 1-kilogram stationary ball B. Which statement is true of the motion of the balls if the collision is elastic

Answer 1

Answer;

D. The balls separate and move in opposite direction.

Explanation;

• This is an example of perfect elastic collision where there is no net loss in kinetic energy as a result of collision.
• In this type of collision both kinetic energy and momentum are conserved. Therefore, when the ball A hits a stationary ball B, they bounce of each other travelling in opposite direction.
