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

A 5.50 kg block (m1) is connected by means of a massless rope to a 3.15 kg block (m2). The pulley is frictionless. Calculate the maximum value for the coefficient of static friction, if the 5.50 kg block is to begin sliding.

The diagram is attatched to the post.

2. Relevant equations

Friction coefficient = (Frictional Force)/(Normal Force)

Acceleration = (m2*9.8)/(m1 + m2)

Of course, Force = mass*acceleration

3. The attempt at a solution

Acceleration = (m2*9.8)/(m1 + m2)

Acceleration = 3.5688 m/s^2

3.5688*5.5 = 19.6284 N = frictional force

Normal force = 5.5*9.8 = 53.9 N

19.6284/53.9 = .36416

I know that the answer isn't right, what am I doing wrong?
