(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A mass [tex]m_{1}[/tex] is hanging from a light cord which is strung over a pulley of moment of inertia, I, and radius [tex]R_{0}[/tex] and connected to a mass [tex]m_{2}[/tex] which is sliding on a rough horizontal surface with coefficient of friction [tex]\mu_{k}[/tex].

a) What is the acceleration of the system?

b) What are the tensions in each part of the cord?

All help is appreciated! :)

2. Relevant equations

[tex]\Sigma[/tex]F = ma

[tex]\Sigma\tau[/tex] = m[tex]R^{2}\alpha[/tex]

3. The attempt at a solution

I started by trying to sum up all the forces and torques but I don't know where to go from there.

[tex]\Sigma F_{x} = T - \mu m_{1}g = (\mu m_{1} + m_{2})g = ma[/tex]

[tex]\Sigma F_{y} = T = m_{2}g[/tex]

[tex]\Sigma \tau = rF_{x} + rF_{y}[/tex]
