A lumberjack (mass = 94.4 kg) is standing at rest on one end of a floating log (mass = 279 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +2.64 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log (again relative to the shore) just before the lumberjack jumps off? (b) Determine the velocity of the second log (again relative to the shore) if the lumberjack comes to rest relative to the second log.

A 90-kg lumberjack stands at one end of a 400-kg floating log, as shown in the following figure. Both the log and the lumberjack are at rest initially. The lumberjack then trots toward the shore with a speed of 2.7 m/s relative to the shore. A) What is the speed of the log relative to the shore? Ignore friction between the log and the water. B) If the mass of the log were greater, would its speed relative to the...

The lumberjack and his log Jack, the lumberjack, mass mj, is standing on his favorite log, mass mi, which is floating motionless on the lake. He starts running on the log, reaching a speed of vJJL- 3 m/s, the subscript indicating that it is measured with respect to the log. What is Jack's speed with respect to the shore vjs? Hint: Use Galilean velocity transformations In peace... A cannon is firing shells of mass m, at a muzzle velocity v...
