A man (mass 120.5 kg) is canoeing with his friend (mass 81.6 kg). He had the only paddle but dropped it in the lake. It has drifted just out of his reach along the long axis of the canoe. His friend suggests that if they trade places he might be able to reach the paddle. The canoe moves in the water without any friction or drag. The passengers sit 2.03 meters apart and the canoe has a mass of 48.7 kg. After the passengers switch places, how much closer to the paddle (which does not move) is the end of the canoe?
I'm not really sure where to start or how to go about this problem. Any steps to start out would be appreciated. Thank you :)
