Give me right solution 

The uniform 10-kg bar is supported on the horizontal surface at A by a small roller of negligible mass. If the coefficient of kinetic
friction between end B and the vertical surface is u, = 0.32, calculate the initial acceleration of end A as the bar is released from rest
in the position shown. The acceleration is positive if to the left, negative if to the right.
Assume L - 1.8 m, e-34.
Answer: oA
m/s2
