After stealing a 20 kg bag of oranges, a 80 kg thief finds himself at rest on a frozen lake. He attaches himself to the bag of oranges with a long rope and pushes himself off from the bag by giving himself a rightward velocity. When the rope runs out: a. the thief and the bag of oranges will move to the right because the thief has a larger mass
b. the thief and the bag of oranges will move to the left because the thief has a larger mass
c. the thief and the bag will stop the thief and the bag of oranges will move to the right because the thief has a larger kinetic energy
d. the thief and the bag of oranges will move to the left because the thief has a larger kinetic energy
