Please Please Please Help Me!
Two skaters (A and B) are in contact with each other and start from rest on frictionless ice. They push off each other with skater A exerting a constant force on skater B while they remain in contact. The skaters then move apart and are no longer in contact. The mass of skater A is smaller than the mass of skater B. Complete each statement with less than, greater than or equal to.


When they no longer are in contact, the magnitude of the momentum of skater A is ________ the magnitude of the momentum of skater B.

While they are in contact, the

Answer 1
