Homework Help: Quick question i'm having touble with

  1. Oct 5, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    refer to 1.

    3. The attempt at a solution

    The answer is 9.1 I've done everything from adding the two equations, to plugging in values im completely stuck. I can find the tension if i solve for acceleration first. But without knowing the acceleration how do you find tension?

    Isn't the acceleration the same for both blocks, so by rearranging the equations to eliminate a you could find T?

    Also, is the coefficient of friction intentionally only to be applied to the block on the right?

    yes i should've mentioned that

    The coefficient only applies to the right block.

    Well i know how to do find T if i find a first. But i was wondering if there was a way to find T before finding a.

    Show us the major steps you took to do that: 'find a first'.
