zero was not right, haha i have one more try. heres the full question...

Two identical carts—A and B—initially are moving on frictionless air tracks. The initial speed of cart A is twice that of cart B. You then exert the same constant force on the two carts over 1 second. One second later, the change in momentum of cart A is...

 

Just want to kill my ear drums after hearing that.

 

Answer 1.

EDIT: Also that's a guess as I thought the answer was Zero as well.

 

I know! well it was not one either. Oh well, no more trys on that problem

 

A wood block rests at rest on a table. A bullet shot into the block stops inside, and the bullet plus block start sliding on the frictionless surface. The momentum of the bullet plus block remains constant

Last one :/

 

What he said! It's not enough info to determine.

 

just ordered my pack rack!!!

 

No more school work for me. I already gradumatated once.

 

well, i didn't finish that assignment too well

 

after the bullet stops!

 

Congrats!

 

Thanks man. Pretty excited. Whits a little mad but oh well.

 

this one took me forever, but i agree, not enough information to determine.

i almost think when the bullet is slowing down, because if its slowing down, it has already hit the block and the block would start moving once the bullet hits the block? the bullet doesnt have to be completely stopped for the block to start moving.

 

At the point the bullet stops, they are both moving at the same rate of speed. Before that, the bullet is moving just a tad faster because it is moving into the block.

 

dam you sure are right! at least i think....

 

that is literally what i do at home when I'm doing homework

 

Anyone have experience with eibach springs from toytec snapping!? Wtffff

 

can you guys tell me anything about the deer valley estate area at 101 and I17 north phoenix? good place to live?

 

One of the nicest places man

 

you don't say. could you elaborate. there maybe a job opportunity in that area for me.
