A 30-kg child stands at one end of a floating 20-kg canoe that is 5.0-m long and initially at rest in

the water. The child then slowly walks to the other end of the canoe. How far does the canoe move

in the water, assuming water friction is negligible?

Please show step by step and explain.

    Jane is trying to get one of the pink flamingos out of the LSU lake. She has brought her 4 m long canoe (with mass Mc = 30 kg) into the water so that the front edge of the canoe is very close to the flamingo. Jane (with mass mJ ) is standing at the other end of canoe, which is 3 m away from the dock. She then starts to walk in the canoe, towards the flamingo. Ignoring water...
