A 0.35 kg block is being pulled across a flat, level surface by a horizontal string. When the tension in the string is 1.8 N, the block's acceleration is 0.75 m/s2in the same direction as the tension. What is the coefficient of kinetic friction between the block and the surface? For your physical representation, draw a free body diagram of the forces acting on the block. Representation:
