Ball A has a mass of 2 kg, and is traveling at 2 m/s to the right. Ball B has a mass of 3 kg, and is traveling at -4 m/s (to the left). The balls collide, and Ball A moves off to the left at -5 m/s. What is the momentum and velocity of Ball B after the collision? Please show your work!

Aspectroscope breaks light up into its colors, allowing scientists to analyze light from the solar system and universe. by studying the spectral line patterns, widths, strengths and positions, scientists can determine the speed, position, and of celestial bodies. a) age b) origin c) rotation d) temperature
