The two sleds shown below are about to collide. When they collide, they bounce off each other and no energy is lost. The kinetic
energy of sled A is 39,561 J just after the collision. What is the kinetic energy of sled B after the collision? (Note: The potential energy of each sled after the collision is 0 J.)
