Q. A 50 kg woman stands on the back of a 6 m long, 125 kg raft that is floating at rest in still water with no friction. The raft is 0.50 m from a fixed pier.

Where does this energy come from, and where does it go when the woman stops at the front of the raft? (Select all that apply.)

On land, the woman puts a lead shot 6 m. She stands at the back of the raft, aims forward, and puts the shot so that just after it leaves her hand, it has the same velocity relative to her as it does when she throws it from the ground. Where does the shot land?
