Determination of recoil velocity of a raft.

A 55 kg swimmer is standing on a stationary 210 kg floating raft. The swimmer then runs off the raft horizontally with a velocity of +4.60 m/s relative to the shore. Find out the recoil velocity that the raft would have if there were no friction and resistance because of the water.
