However, the following will actually happen (ignore the friction of the water or air on the boat or the man):Select one:a.None of the above.b.The boat doesn't move and the man moves to the right.c.The man actually stays still while the boat moves toward the left.d.The man only moves a short distance to the right while the boat moves a larger distance to the left.

If a man jumps off a boat towards the shore, then the boat:Moves away from the shoreMoves towards the shoreRemains stationaryMoves vertically downwards only

A 49.0 kg person is standing in a canoe while it moves forward at a constant speed of 7.40 m/s. He jumps off the canoe, and just after the jump he has a speed of 1.20 m/s in the same direction he was moving. Just after the jump, the canoe has a speed of 12.5 m/s. What is the mass of the canoe? 59.6 kg 21.2 kg 11.5 kg 4.70 kg

Canoe walk concept  |  ProblemOn a calm day at the lake, you observe a person in a canoe, floating initially at rest.  Then the person stands up and walks toward the front of the canoe—to the right from your perspective. Why does it behave this way?Group of answer choicesFor every action there is an equal and opposite reaction.Net momentum is a constant.Newton's 2nd law says they must have equal and opposite forces.The impulse on person is zero.The impulse on the canoe is zero.
