I really need help on this question. I need it to be solved correctly because I have one more try. I need help on the first problem specifically. Thank you.

Robert and his younger brother Jake decide to go fishing in a nearby lake. Just before they cast off, they are both sitting at the back of the boat and the bow of the boat is touching the pier. Robert notices that they have left the fishing bait on the pier and asks Jake to go get the bait. Jake has a mass of 52.0 kg and an arm reach of 50.0 cm, Robert has a mass of 83.0 kg, and the boat has a mass of 82.5 kg and is 2.70 m long. Determine the distance the boat moves away from the pier as Jake walks to the front of the boat. Ignore any friction between the boat and the water. It should also be noted that since the boat is not symmetrical, the center of mass of the boat is not at the midpoint of the length of the boat. 0.7 What is the initial momentum of the system (boat and boys)? Is momentum conserved? Does the center of mass of the system move? Can you write an expression of the center of mass of the system for the initial (both boys at the back of the boat) and final (Robert at the back and Jake at the front of the boat) situation? m Once Jake reaches the front of the boat, will he be able to retrieve the bait, or will Robert have to row the boat back to the pier? O Jake is able to reach the bait. Jake is not able to reach the bait. There is not enough information to tell. Additional Materials LE Reading
