Two blocks connected by rope: acceleration when 60N force applied to one

[caffe]

Hello friends
I have a problem.please give me the answer.
Two blocks of masses 6kg and 4kg connected by a rope are resting on frictionless floor.If an instantaneous force of 60N is applied to 6kg block for only a second.Then what is the acceleration of the first and second block.Is the acceleration of first and second box same or different and why?please reply me .[The force applied is parallel to the rope in between 6kg and 4 kg and pulls the blocks]

The acceleration will depend on the direction of the force.
if it is in the direction away from the 4kg block then the acceleration will be the same.
