That's true...but since none of the equations call for the friction force, let alone the coefficient of friction, how do I inocrporate it into the problem?
Homework Statement
An object of m=0.85kg is on a table. It is attached via pulley to a hanging object of m=0.42kg. The pulley is a hollow cylinder of mass 0.35 kg, with an inner radius of 0.02m and an outer radius of 0.03m, and it turns without friction. The coefficient of friction between...
