Question
For this problem, take right as the positive direction and left as the
negative direction.
Bouncy ball a of mass ma =2 kg is moving to the right at 2 m/s when it
collides with and bounces off a second ball of mass mb = 3 kg moving to
the left at 3 m/s. After the collision, the ball b is moving to the right at 1
m/s.
What is the final velocity of ball a?
Be careful to enter the correct +/- sign, and round your answer to one
decimal place.
0.5 m/s
-0.5 m/s
-12.5 m/s
-4.0 m/s
4.0 m/s
12.5 m/s
