Mb*V1 + Ma*V2 = Mb*V3 + Ma*V4.
5*3 - 10*3 = 5*V3 + 10*2,
-15 = 5V3 + 20,
V3 = -7 m/s = 7 m/s to the left.
The mass of ball A is 10 kilograms and the mass of ball B is 5 kilograms. If the initial velocity is set to 3 meters per second for each ball, what is the final velocity of ball B if the final velocity of ball A is 2 meters per second?Use the elastic collision equation to find the final velocity of ball B. Assume ball A initially moves from right to left and ball B moves in the opposite direction. Identify each mass, velocity, and unknown. Show your work, including units, and indicate the direction of ball B in your answer.
