trolley question - physics another one!?

Question

Two men sitting on wheeled supermarket trolleys

In scenerio Mr A pulls on the rope, other end is tied to Mr B trolley. He isnt holding it.

i) who will move towards who? Will one move and other not if so who otherwise will both move towards each other?
ii) have to choose between the following:
the rope exerrts a force on B not on a
the rope exerts a force on A not on B
THE rope exerts force on both and forces same size
the rope exerts force on both, force on B is bigger
the rope exerts force on both, force on A is bigger

Answer 1

1) depends on who has the trolley with the wonky wheel ...

IF, both A & B have exactly the same co-efficient of resistance and inertia, THEN A & B will both move towards each other at the same speed.

2) THE rope exerts force on both and forces same size (of course)

Answer 2

1) If Mr A is lighter than Mr B then Mr A's trolley will be pulled towards b trolley if its otherwise then answer is vice-versa
However if both r of same mass, both the trolleys'll move towards each other (considering same mass of both trolleys)!

2) the rope exerts force on both but which force is bigger depends upon the weights of the Mr a and B!


that it! does it help?!
