Question
A blue ball travelling at 2m/s collides with a red ball at rest on a table. After they collide, both balls move in the same direction. Both balls have the same mass. If the blue ball continues to move with a reduced velocity of 0.2m/s, what is the velocity of the red ball?
Answers
momentum is conserved
momentum lost by the blue ball is acquired by the red ball
momentum lost by the blue ball is acquired by the red ball
