Her trademark two-footed flying kick, Xena (65 kg) swings from the rope and strikes the 100 kg bad guy in the breast. She comes to a stop and regains her balance when the collision happens. When the effects of friction are taken into account, we may be confident that the following will be true: The kinetic energy is conserved. O Momentum and kinetic energy are not conserved. Both the energy and the motion are maintained. The momentum may be maintained.
