Atwood pulley problem

A block of mass 2.30 kg is accelerated across a rough surfaceby a light cord over a small pulley. The tension T in the cord ismaintained at 10.0N and the pulley is0.110 m above the top of theblock. The coefficient of kinetic friction is 0.330.a.) Determine the acceleration of the block when x=.4 m.b.)Find the maximun value of the acceleration and the positionx for which it occurs.c.) Find the largest value of x for which the acceleration iszero.I believe that I am getting the wrong amount, for the numberof forces acting on the mass. This problem is at an angle of 15.4deg from the horizontal.
