Two pucks are initially moving along a frictionless surface as shown in the diagram. The pucks have mass m_(1)ltm_(2) and begin with equal magnitude of momentum. A constant force vec(F) is applied to each puck direactly to the right for the same amount of non - zero time. After the pushes are complete, what is the relationship for the size of the moments of pucks ( p_(1) and p_(2) ) ?
