A dog of mass Md is standing on a raft so that he is a distance xdgi = L from the shore. He walks a distance Δxdb = d on the boat toward the shore and then stops. The boat has a mass of Mb. Assume no friction between the boat and the water. How far is the dog from shore when he stops moving?

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?
