Homework Equations
T=Iα, F=ma, I=0.5*m*r^2, Friction=u*N
The Attempt at a Solution
I used the torque equation to get Tension = mcylinder*a/2, and then plugged that into a force equation for the block.
mblockgsin(30)-Tension-Friction=mblock*a
so
mblockgsin(30)-mcylinder*a/2-μmblockgcos(30)=mblock*a
I ended up with μ=0.36. Just wanted to check my answer because I never ended up using the radius of the cylinder (it canceled out), so I was wondering why it was given.
