A 5-gram marble moving at 5 m/s [N] collides with a second marble in an off-center collision.
0005
Suppose the second marble has a mass of 5 grams and is initially at rest. The
collision is elastic and the final speed of the second marble is 4.0 m/s.
4) What is the final velocity of the first marble?
