A 30-kg child stands at one end of a floating 20-kg canoe that is 5.0-m long and initially at rest in
the water. The child then slowly walks to the other end of the canoe. How far does the canoe move
in the water, assuming water friction is negligible?
Please show step by step and explain.

A 55.0 kg woman stands up in a 70.0 kg canoe of length 5.00 m . She walks from a point 1.00 m from one end to a point 1.00 m from the other end. If the resistance of the water is negligible, how far does the canoe move during this process?

Part A
If you ignore resistance to motion of the
canoe in the water, how far does the canoe move during this
process?

A 70-kg man is standing on the end of a 250-kg log that is floating in the water. Both the man and the log are at rest, and the log is 3.0 m long. If the man walks to the other end of the log, how far will the log move in the water? Ignore any forces exerted on the log by the water.

A 90-kg lumberjack stands at one end of a 400-kg floating log, as shown in the following figure. Both the log and the lumberjack are at rest initially. The lumberjack then trots toward the shore with a speed of 2.7 m/s relative to the shore. A) What is the speed of the log relative to the shore? Ignore friction between the log and the water. B) If the mass of the log were greater, would its speed relative to the...
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 275 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just...
A lumberjack (mass = 94.4 kg) is standing at rest on one end of a floating log (mass = 279 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +2.64 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log (again...
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 215 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +4.0 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just...
A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 260 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +3.5 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water. (a) What is the velocity of the first log just before the lumberjack jumps...
In Figure (a), a 4.4 kg dog stands on a 14 kg flatboat at a distance D = 7.3 m from the shore. He walks 1.7 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore. (Hint: See Figure (b). The dog moves leftward and the boat moves rightward, but does the center of mass of the boat + dog system move?)
