Three objects are connected by weightless flexible strings as shownin the figure below. The pulley has no appreaciable mass orfriction, and the string connected to the block on the horizontalbench pulls on it parallel to the bench surface. The coefficients of friction between the bench and the block on it are μs=.660and μk=.325. You observe that this system remains at rest.

Find 

a) the mass of A and 

b) the friction force on the block on the bench.
