Two masses are connected to two pulleys via ropes.The mass of the hung mass is 16kg and the mass of the object on the slope is 8kg the slope has an angle of 37 degrees. Pulleys 1 has a mas of 6 kg and Pulley 2 has a mass of 4 kg. using the picture and the given info find the following (the kinetic friction coefficient is 0.23)
a) Angular acceleration for the two pulleys
b) the linear acceleration for each pulley
c) the force of each of the ropes that are connected to the pulley

Homework Equations

angularacceleration=a/r
Torque=F.r
angularacceleration=Torque/I

The Attempt at a Solution

angularacceleration=torque/i
((m1g-Ft1)r1-(-Fk-m2g×sin37+Ft2)r2)/(0.5)(6)(0.15)^2+(0.5)(4)(0.1)^2
as you can see I already have 3 variables what should i do?

You should provide a better image, one that is oriented properly, or describe the pulley arrangement in better detail in your text. It's preferable to upload images to PF rather than to some off-site storage area.

That is very hard to decipher. The reader has to reverse-engineer the expressions to figure out what all the variables are and what the numbers represent.
Either use LaTeX or, at the least, use the superscript and subscript buttons provided.
Define all your variables. For the constants, it is better to invent and define variables to represent them, only plugging in numbers at the end. (This has many advantages.) if you must plug in numbers straight away, build the expression up in steps, explaining what you are doing.
