Homework Statement
Gliders C and D, of masses 2kg and 4kg, respectively, collide on a frictionless track. Glider C initially moves to the right with a speed of .6 m/s relative to the track, while glider D is at rest. After the collision, glider C moves to the left with a speed of .2 m/s. System S consists of gliders C and D.
Homework Equations
What is the magnitudes and directions of the momentum vectors for glider C, glider D, and system S before and after the collision?
Is the momentum of system S before the collision the same as it is after the collision? Explain.
The Attempt at a Solution
I was able to find the momentum of glider C before and after the collision using p=mv. I also knew glider D would not have a momentum vector before the collision because it is at rest.
I could not find the momentum of glider D after the collision or the momentum vectors of system S.
