Trolley

[primarygun]

In a trolley-trolley system, two trolleys are linked with a turgid rope.
When there is a force applied, when their accelerations are the same? :!!) :!!) :!!)

Accelerations will be the same only if both have the same mass and whether the force applied is the same to both.....

I'm not sure what a "trolley-trolley" system is, but if two masses are constrained by a taut, unstretchable rope then they will have the same acceleration.
