Ball A has a mass of 0.200 kilograms. Ball A, traveling at a velocity of 2 meters/second in the +x direction, hits a stationary ball B of the same mass. After the collision, ball B bounces off at a positive angle with respect to the +x-direction. Which statement is true for ball A if the collision is elastic?
A.
Ball A follows ball B separately at positive angle with respect to the +x-direction.
B.
Both the balls stick and move together at positive angle with respect to the the +x-direction.
C.
Ball A stops.
D.
Ball A travels off at some negative angle with respect to the +x-direction.
