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 as in Figure P4.26. The 5.00 kg crate lies on a smooth incline of angle 41.0°. Find the acceleration of the 5.00 kg crate.
could you detail how to do the problem....i don' want just the answer....thank you!!!!

You haven't said anything about friction, so it might look like this:

With this type of problem you're using f = ma twice. Once on the smaller block to calculate the driving force. And again on the combined mass to get the acceleration.
Total mass = 15kg
f = ma
a = f/m = 32.1469/15 = 2.143m/s^2
