Xena (Warrior Princess, mass 65 kg) swings from a rope at an armored villain (mass 100 kg) and delivers her trademark two-footed flying kick to his breast plate, knocking him backwards. The collision brings her to a stop and she lands on her feet. Neglecting friction and measuring speeds just before and after the collision, we can expect that, to a high degree of accuracy: Kinetic energy is conserved O Neither momentum nor kinetic energy are conserved. Both momentum and kinetic energy are conserved O Momentum is conserved
