so, i have a problem. see the pic
the question is. if we have, for example 10 balls standin like that, if we move the ball which is on the right, only one will move, the left one. if we move two of them from the right, two of them will move on the left also.
Ft = mv to satisfy the conservation of momentum
The Attempt at a Solution
the solution is that something else is satisfied, i know that the momentum is satisfied but something is missing. please help :-)
thanks in forward
