Dog on a boat center of mass problem
Рет қаралды 35,384
6 жыл бұрынPhysics Ninja looks at a classical center of mass problem involving a dog walking on a boat. The position of the center of mass of the system remains unchanged and the position of the dog with respect to the shore is calculated.

shouldn't mdxd be negative since it is moving in the left direction?

Ah, because the boat moves? I had originally thought 3.7 assuming the boat didn't move.

@@PhysicsNinja my bad....the question which I've got is a dog of mass 10kg is standing on a flat 10m long boat so that it is 20m from the shore. It walks 8m on the boat towards the shore and then stops. The mass of the boat is 40kg and friction between the boat and the water is negligible. how far is the dog from the shore now?......the actual answer is 13.6m but by using your method i got 14m ......actually you didn't calculate the backward motion of the boat that makes the position of center of mass of boat constant i suppose....

The answer is not correct...bz dog & boat are moving opposite to each other from groud observation... So the eqn would be:- 2.4= ◇x(d,G) - { - ◇x(B,G) } So 2.4= ◇x(d,G) + ◇x(B,G)

this is so lame, what ever happened to intuition?

literally no way to visualize wtf you mean by dog relative to ground minus boat relative to ground. that doesnt do anythingto explain even with the picture it doesnt tie anyhing together for the viewer.

listen, lemme tell you something, all these physics channel morons don't know anything about physics, they're just book smart, they're not capable of thinking outside the box, they've memorized every single problem and how to do it whether the method is right or wrong. if this was actual real life, and this exact situation played out, his answer would be completely incorrect.
