A 32 kg boy is standing on a 59 kg raft that is 8 m wide. He walks 6 m from a point 1.0 m from the left edge of the raft to a point 1.0 m from the right edge of the raft. If you ignore resistance of the water to the motion of the raft, how far does the raft move during this procedure
The Attempt at a Solution
i draw a force diagram for it and looks like the one that will effect the movement of the boat is
F = friction force
but I have no idea what the friction constant is. and also will the mass affect the movement of the boat?
and I also don't have any velocity to use the equation of
m1v1 + m2v2 = m3v3
32(v1) + 0 = 91(v3)
