A0.200-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;

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.

all three
