A lumberjack (m= 98 kg) is standing at rest on one end of afloating log (m= 230 kg) that is also at rest. The lumberjackruns to the other end of the log, attaining a velocity of +3.6 m/srelative to the shore, and then hops onto an identical floating logthat is initally at rest. Neglect any friction and resistancebetween the logs and the water.
a- What is the velocity of the first log just before thelumberjack jumps off?
b- Determine the velocity of the second log if the lumberjackcomes to rest on it.
