A straight path is inclined at an angle of 15 degree to the horizontal. A loaded skip of total mass 1500 kg is at rest on the path and is attached to a wall at the top of the path by a rope. The rope is taut and parallel to a line of greatest slope of the path, as shown in the diagram. Calculate the normal and rictional components of the contact force exerted on the skip by the path when the tension in the rope is 2000 N.
After the rope is cut the skip is on the point of slipping down the path. Calculate the coefficient of the friction between the skip and the path
