Okay, so we've got these these ice skaters, right? Um, and they do a lift. Okay, So first we've got this skater. This, I guess, is the guy, right? And they are 50% more massive than the leave skater who is a gal, right? Don't you said there they are. So and this person is going 6.2 meters per second, and they have 50% war mass, So they are 1.5 times the mass of this person. This person is 1.0 times their own mass. They're going a little bit slower, right? Right. And then in the second picture, we've got this guy holding up the second person. There we go. All right. So this, by the way, it would be 1.5 times the mass of this person plus 1.0. So that's gonna this is gonna be two point five times the mass, and we want to know what is that velocity? Right. So they noticed that they haven't told us with the massive this person, So you could either make up a mass. I hope you're cancels, or in this case, it actually will just cancel out right okay, cause it'll be EMS on both sides. Right. Okay, so we were just gonna treat this as conservation of momentum. Remember, momentum is M V. Right. So if we add up all the momentum here, that illegal the momentum there. Right. Okay. So if I go, um, 1.5 AM times 6.2 plus 1.0 m times 5.5, that equals 2.5. And that 2.5, of course, is the 1.5 plus the 1.0 right combined times V. Right. Okay. Noticed that the, uh, we get the red pen of cancellation. You the mass cancels from both terms. Right, Cause have you divided both sides by I am your divide every term on the side in every term, on the side by and remember terms of things with what pluses reminds his behind between between. Right, So it's a 1.5 times. Ah, 6.2 plus one plus zero times 5.5. Devise equal to. And then that's 14.8. Divided by 2.5 5.92 Um, and then you really have to sick things. Seems like maybe we do Yeah, because they've been Yeah. So it's really to six. So we have to say 5.9 meters per second. Yeah. There we go. All right, that's it.
