a 2kg ball is moving rightward at 2m/s when it collides with a 6kg ball that was moving west at a speed of 4m/s. After collision the 2kg ball moves west at a speed of 4m/s. Thw 6kg ball is also moving westward after collision with a speed of 2m/s. Show momentum is conserved. Show whether or not energy is conserved. Based on your answer what type of collision do you think we have?1
I will be happy to critique your work.
