So at the start he will be 1.18 units from the mass. Same if he moves to the end of the boat. I also replyed to someone else my current findings which I would appreciate if you would take a look at to see if I'm in the right thought process.

I just found that if I do (0(179)+3.1(57))/(179+57) I would get 0.7487. Then I did 3.1-0.7487 and got 2.35. To summarize my thought process I realized that because the man is now on the other side, he would be at the point 3.1. Now the boat would be at the 0 point instead. I don't have any...

So for part 1 I used the center of mass equation and did this: (57(0) + 179(1.55))/(179+57). Then for part 2 I assumed would be the same answer...and I just realized I don't know why...

Here's a photo: Also my apologies I'm really trying to figure out based on previous replies how to utilize these hints. I'm really bad at physics for some reason compared to differential equations lol

Alright so the center of the mass cannot move since there are no external forces. I'm thinking maybe I need to create some type of equation with perhaps the momentum of the boat being equal to the momentum of the man? I'm trying to figure out how I would go about doing this since I need to make...

Alright so he does exert a force on the boat when he goes from standing to moving. I'm thinking that this force would have to do something with mass times velocity or mass times an acceleration of some sort correct? And what would such a force do? Would it end up moving the whole boat to the...

Also, so the conservation of momentum law should be applied here right? I can't think of any horizontal forces that would come into play here. Lastly, this would mean that the motion of the center of mass would be to the right?

How come velocity is at play here? Also, so the conservation of momentum law should be applied here right? I can't think of any horizontal forces that would come into play here. Lastly, this would mean that the motion of the center of mass would be to the right?

Hey guys, So with some help from classmates I have seen the way I am supposed to approach this problem starting from number 3, which is to use the above equation. But the problem is I have never seen this equation before in class! I don't know what the purpose of the equation is, where it was...
