## Homework Statement

block 1 lying on an inclined plane is connected to block 2 by a cord passing over a pulley.

the coefficient of kinetic friction between block 1 and the plane is .21 and block 1 and 2 are 2.6 kg. As block 2 moves down, determine the magnitude of the acceleration of block 1 and block 2 given θ=26˚ (in the diagram, block 2 isn't on a plane, just hanging)

## Homework Equations

F=ma?

9.8sin26?

## The Attempt at a Solution

we never learned this type of problem in class, but i found an equation in the back of my textbook g (m1sinθ-m2)/(m1+m2)

i'm guessing m1 and m2 are mass1 and mass2 so when i solved it i got 1.16. this problem is from an online site masteringphysics.com and eventually i guessed 1.8 and it was right, but i'd like to know how to actually do the problem. don't need to answer right away
