(a) A canoeist (person) of mass mp sits at rest at the back end of a canoe. The canoe has a length L, a mass me, and is initially at rest in the still water of a lake with its front end a distance d; from the dock. Then the canoeist realizes that the paddle is still on the dock, and carefully moves to the front of the canoe. After the person reaches the canoe's front end, what will the distance df of the canoe's front end be from the dock? (b) Evaluate your result for mp: = 72 kg, mc = 21 kg, L= 4.2 m, and di = 0.2 m. Will the dock be within reach from the front of the boat? Check: For mp = 56 kg, mc = 23 kg, L = 3.8 m and di = 0.50 m you should find df = 3.2 m.
