In the example i have A block (mass m1 = 22.1 kg) is on a surface inclined at = 33°. It is connected to a mass m2 = 11.2 kg by a massless cord passing over a pulley. The coefficients of friction are µk = 0.15 and µs = 0.25(adsbygoogle = window.adsbygoogle || []).push({});

It asks me for the magnitud of the friction.

After looking at this problem I solved for Fs= 45.4 & the Fk=27.24. So i said that Fk<Fs. Therefore there is no acceleration. I really dont know where to go from there to get the magnitud of this friction. That its not even moving the block.

Please any sugestions??
