Homework Statement
A block with mass m1=2.00kg is on a flat surface and a block of mass m2=6.00kg is on an incline and they are connected by a massless string over a pulley in the shape of a solid disk with a radius R=0.250m and mass M=10.0kg. The angle of the incline is [tex]\Theta[/tex]=30o and the blocks are allowed to move. The coefficient of kinetic friction is 0.360 for both blocks. Determine the acceleration of the two blocks and the tensions in the string on both sides of the pulley.
Homework Equations
[tex]\Sigma[/tex]Fx=T-[tex]\mu[/tex]k+Tcos30=ma
[tex]\Sigma[/tex]Fy=m1g+m2g-Tsin30=ma
[tex]\Sigma[/tex][tex]\tau[/tex]=RT1-RT2=I[tex]\alpha[/tex]
I think I'm accounting for all of the forces I've come up with in my free body diagram, but I'm not sure if I should have a force of friction in the y direction.
