A 100 kg man stands up in a 50-kg boat of length 5m. He walks from a point 2 m from the right end to a point 1 m from the left end. If resistance to motion of the boat in the water can be neglected, how far does the boat move during the process? Please give steps!
Homework Answers
Hi,
Hope you are doing well.
You can use a simple formula to solve these kind of problems. The center of mass shift or the distance boat moves is given by,
Where given that,
Mass of man, m=100 kg.
Mass of boat, M=50 kg.
Distance he travelled on boat, L=2m-1m=1m

canoe 5.00
m long. She walks from a point 1.00
m from one end to a point 1.00
m from the other end (the figure (Figure 1) ).
Part A
If you ignore resistance to motion of the
canoe in the water, how far does the canoe move during this
process?

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?

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?)

A person weighing 60 kg is standing at one end of a flatboat so that he is 10 m from the shore ( see fig. below). He walks towards the other end of the boat until he arrives at the middle of the boat. He then finds out he is 1.2 m farther from the shore than before. The flatboat weighs 180 kg and one can assume there is no friction between it and the water. a) How far away...

A raft of length Land mass M is a distance d from the dock. At the end closer to the dock stands a person of mass m. For the purpose of getting some numerical values assume that M = 200 kg, m = 50 kg, L = 10 m, d = 4 m. a) As the person walks the center of mass of the system doesn't change. Explain why. b) The person walks to the other end of the raft....

A person with mass m1 = 61 kg stands at the left end of a uniform beam with mass m2 = 104 kg and a length L = 2.6 m. Another person with mass m3 = 68 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 8 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate...

Two people pull a 107 kg. boat from opposite sides of a narrow river with ropes that make a 60 degree angle with the velocity of the boat.. Each man pulls with equal force. The motion of the boat is opposed by a drag force from the water of 118 Newtons. If the boat accelerates to the right at a rate of 3.5 m/s2, with what force must each man be pulling his rope? Give your answer in Newtons.
