An 76 n box of oranges is being pushed across a horizontal floor. as it moves, it is slowing at a constant rate of 0.90 m/s each second. the push force has a horizontal component of 20 n and a vertical component of 25 n downward. calculate the coefficient of kinetic friction between the box and floor.
express your answer using two significant figures.
