Hey I'm having a bit of difficulty determining what the force of friction is for the following problem:



Oh but the mass of the hanging mass is 4.0 kg. I drew it wrong :|

Find the minimum coefficient of static friction between the small and large block that would allow it to stay in place as the system accelerates..


I know that the acceleration of the system is 0.93 m/s^2 up the incline... and that the Force of Normal of the small block is 10.08... But What is the force of friction?..

Any help would be greatly appreciated! Sorry for the crude drawing

Hi,

First of all i think the drawing is well done.

Secondly is you look in this section K&D you will find hundreds of these questions>

hint: look at threads started by christina

is the ans 11.48 newton?
unlike paul, i found it a much complicated problem with a shower of forces.,
