Tension and Acceleration in a Pulley System

[wowdusk]

Homework Statement

Two packing crates of masses m1 = 10.0 kg and m2 = 5.00 kg are connected by a light string that passes over a frictionless pulley . The 5.00 kg crate lies on a smooth incline of angle 40.0°. Find the acceleration of the 5.00 kg crate and the tension in the string.

Homework Equations

i know there is only 1 tension because they area attached by a frictionless string, i just don't know where to go from there

The Attempt at a Solution

What are the forces acting on the 5 kg block on the incline?

i told of everything the question gave me for info

Like, what forces act on the crate placed on the smooth incline?
Write the force equations and calculate.

thats where i am stuck...I'm kinda new to this tension stuff

Ok, you must have read that tension always acts away from the body. The weight of the body will also have an effect on its motion, in this case. Keeping these points in mind, work out the possibilities and inform us of the developments.
