A 53-kgwoman contestant on a reality television show is at rest at the south end of a horizontal 149-kgraft that is floating in crocodile-infested waters. She and theraft are initially at rest. She needs to jump from the raft to aplat form that is several meters off the north end of the raft. Shetakes a running start. When she reaches the north end of the raftshe is running at 4.1 m/srelative to the raft. At that instant, what is her velocity relative to the water?
