A 25 kg box is along a horizontal floor and a force of 400 N pushes the box with an angle of 50 degree with the horizontal. Starting from rest, the box achieves a velocity of 2 m/s in a time of 4 seconds. Find the coefficient of sliding friction between the box and the floor. Help please. I need a solution
