so i got 2 little cars, one of them has more mass than the other one.BOTH CARS MOVING and impact. Which one pushes and which one pulls? (AKA which one has the + Newtons and which one has the - ones? )

the one resting got the positive ones, i believe.. gosh, didnt have physics for like 4 years now
Next question:
i got 2 cars connected by a rope. each car has another rope pulling it in different directions (one car being pulled left and the other one being pulled right) by a hanging mass that is equal for each one. which one has + tension and which one has - ?

and everyone said the opposite of that :P
pls
Im having to do Mechanical engineering as part of my electrical engineering course, Having to work out UDL's etc sucks cock!
gimme the answer, bitch!
Dependes on each cars speed... if they are both goin at the same speed and no acceleration, then the car with the greater mass would be the one that pushesOK

If the car with the lower mass is goin at higher speed, you can calculete the Car's Newtons by a formula that you are supposed to know which I forgot.
It goes something like (speed x mass (or weight)) if the acceleration is zero
If you consider Acceleration its a whole different formula in which you'll have to use Factors like Time and probalily you'll work in a vacum
I didn't understood ths questionNext question:

get on msn and tell me there :P
When i have to work out things like this i have to do C.W.M = A.C.W.M for the points at which moments occur. The question is quite open ended and dont quite get what your askinggimme the answer, bitch![/b]
Either you are not quoting the questions correctly or they are plain incorrect. What the hell does "pushing and pulling" mean with regards to physics? it doesn't even say the velocity of the 2 cars. If its a headon collision then the heavier car has more momentum and so continues in the same direction whereas the lighter car will travel in the reverse direction.
As for the second question, again it doesn't give you enough information, or it is a trick question. Both cars would exert the same tension on the ropes if they are the same mass.
