James runs along the surface of a frozen lake towards Alex. Alex is stationary on both slide an inner tube. James then jumps on the inner tube with Alex and they forward in the same direction that James was initially running in. Ignoring any friction from the surface of the ice, how does the system's momentum that contains both James and Alex on the inner tuber change from James jumping on the tube? a. The system's, momentum increases b. There is not enough information to be able to determine if the system's momentum will change. c. The system's momentum will change depending on their difference in masses. d. The system's momentum doesn't change. e. The system's momentum decreases
