What Is the Acceleration of Masses on an Inclined Plane with Friction?

[leisiminger]

Objects of Masss m1= 4kg and m2 = 9kg are connected by a light string that passes over a frictionless pulley. Object m1 = is held at rest on the floor, and m2 rests on a fixed incline of 40 degrees. The objects are released from rest, and m2 slides 1 meter down the <b>rough</b> incline in 4 seconds.
a) determine the acceleration of each object using a kinematic equation for constant acceleration b) the tension in the string, and d) the coefficient of kinetic friction between m2 and the incline.

I'm really having trouble finding the acceleration, I'm not sure if I am looking too deeply into it.
I've tried so many different ideas i don't know where to begin :(

It suggests using a kinematic equation for constant acceleration. It might be an idea to write down all the kinematic equations for constant acceleration and see what you can do with them.
