To find the velocity of ball A after the
elastic collision, we will use the formulas for the velocities of objects after
an elastic collision in one dimension.
Given:
Mass of ball A (): 2 kg
Mass of ball B (): 3 kg
Initial velocity of ball A (): 6
m/s
Initial velocity of ball B (): 0
m/s (since ball B is stationary)
According to Momentum and Kinetic Energy
Conservation, we have
We can solve:
