G A lighter ball A with momentum PA=5.0 kg∙m/s in positive x-direction approaches a heavier ball B at rest before the collision. After this head-on collision, the lighter ball bounces straight back with a momentum P’A=2.0 kg∙ m/s in negative x-direction. What is the magnitude of the heavier ball B’s momentum change?
