A 87 kg lumberjack stands at one end of a 393 kg floating log, as shown in Figure 9-17. Both the log and the lumberjack are at rest initially.(a) If the lumberjack now trots toward the other end of the log with a speed of 2.7 m/s relative to the log, what is the lumberjack's speed relative to the shore? Ignore friction between the log and the water.
