Hello!

I have just started physics here in Norway, and we have a home assignement due to friday. I sat all yesterday trying to figuer out what friction coefficient to use in my assignment. Here is the assignment:

Two objects are lying on an horizontal table, tied together with a very light rope, object 1 has the mass of 2Kg and object 2 has the mass of 4Kg.

Object one has friction coefficient = 0.1

Object two har friction coefficient = 0,15

The Force applied on the rope tied to object 2 has a force of 60N...

Object 1----------object 2----------------> F=6N

Do i calculate with 0.25 as a friction coef.? or both individually intergrated into F-(Mju*g+(m1+m2)/(m1+m2) . To find the acceleration

Please give me some hints.

Hopefully you understand my english :)

thanks
