Question

Two skaters, Juliana (70 kg) and Cameron (100 kg) are at rest on the ice and are standing facing each other. Juliana pushes off of Cameron, and the two skaters move apart. Which of the following statements about this situation are true. Check all that apply. Cameron's momentum does not change during the push off. The total combined momentum of Juliana and Cameron does not change during the push off. During the push off, Cameron and Juliana exert equal but opposite forces on each other. The final momentum of Juliana is equal in magnitude but opposite in direction to the final momentum of Cameron. Juliana's momentum does not change during the push off. The final velocity of Juliana is equal in magnitude but opposite in direction to the final velocity of Cameron. During the push off, the change in momentum of Cameron is equal in magnitude but opposite in direction to the change in momentum of Juliana.

Explanation / Answer

The total combined momentum of Juliana and Cameron does not change during the push off During the push off, Cameron and Juliana exert equal but opposite forces on each other. The final momentum of Juliana is equal in magnitude but opposite in direction to the final momentum of Cameron. During the push off, the change in momentum of Cameron is equal in magnitude but opposite in direction to the change in momentum of Juliana.
