Question

application of conservation of momentum​

Answer 1

Momentum is conserved because the net external force on the puck-goalie system is zero. We can thus use conservation of momentum to find the final velocity of the puck and goalie system. ... Once the final velocity is found, the kinetic energies can be calculated before and after the collision and compared as requested.
