1. Each kid would have a momentum on 120 each ( 30kg*4m/s) 2. Would each kid have equal momentum?, meaning 75 each?

Well 1. The mans momentum would be his mass(velocity)= -150 because he is moving along the negative x axis. 2. The momentum of the 2 kids must have a momentum of 150, which will make them all stop once they collide.

No that is right, they do stick together. I just don't really know what to do with this problem and I was just throwing out some ideas I came up with. I am pretty confused at the moment with it though.

So when finding the new velocity when the two kids collide, do I find the center of mass velocities in the x and y components and then find the magnitude of that to find their new velocity?, or do I need to use cosine and sine in my equations and find the velocity that way. If i did use cosine...

But you don't know the direction they are comming from, how would you figure that out?, because you find the angles at the end of the problem, that is what the question wants...

Hi, I am having problems with a particular question it says: Two 30kg children, each with a speed of 4.0m/s, are sliding on a frictionless frozen pond when they collide and stick together because they have Velcro straps on their jackets. The two children then collide and stick to a 75kg man...

I was just wondering if anyone knew how to comvert Newtons to pounds. If anyone knows it would be greatly appreciated. Thanks

Newtons to Pounds I was just wondering how you convert Newtons to pounds If anyone knows this it would be muchly appreciated Thanks

This seems like a very easy problem, if I'm approaching it properly. You would have your 3.0N down as your mg and the T would be 1.0N up. Would that mean that the megnitude would be 2.0N downward as a final answer?

A block with a weight of 3.0N is at rest on a horizontal surface. A 1.0N upward force is being applied to the block by means of an attached vertical string. What are the magnitude and the direction of the force of the block on the horizontal surface? I was wondering what it meant by the...

I'm in an engineering linear algebra class and am struggling with the section of complex functions, if anyone has any information that could help me with the understanding of this it would be greatly appreciated. Thanks

I had no reason to believe it would be around 3, it was just it seemed 36m/s^2 would be too high of a number. Thanks though for all the help with this problem, I appreciate it.

Would 36.96 be the correct acceleration?

Doing that gives you an acceleration of 36.96m/s^2, just seems like it should be more like 3

Yes, i hope so, but one other question, I rearranged the velocity and displacement equation to solve for acceleration and have calculated the mass of the fish, but i get a really large acceleration, is it because i converted the 13cm to m?, isn't that was is always done?, or am I going wrong...
