You are standing at the very rear of the raft of length L = 6.4 m and mass M = 132 kg which is at rest in a lake with its prow mere 0.50 m from the end of the pier. Your mass is m = 59 kg. Avoid frictional forces among the raft and the water. Determine how far from the end of the pier is the center of mass of the you-raft system?
