A lumberjack with a mass of 60.0kg runs from one end of a log to the other. The log is 8.00m and the right end of the log is 5.00 m from the riverbank. A. After covering the length of the log, the lumberjack finds that he is now 7.00 m from the shore. What is the displacement of the lumberjack relative to the shore? B. An observer on the shore finds that the time it took the lumberjack to cross the 8.00 m log was 1.75 s. What is the average velocity of the lumberjack relative to the water? C. What must be the mass of the log? K
