A 15-pound box sits at rest on a horizontal surface, and there is friction between the box and the surface. One side of the surface is raised slowly to create a ramp. The friction force f opposes the direction of motion and is proportional to the normal force F exerted by the surface on thebox. The proportionality constant is called the coefficient of friction, u. When the angle of the ramp. 0, reaches 25°, the box begins to slide. Find the value of u15 poundsThe value of u is(Do not round until the final answer. Then round to two decimal places as needed.)
