Homework Help: Quick question i'm having touble with

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'.
