Find the force required to move a load of 30N up a rough inclined plane, applied parallel to the plane. The inclination of the plane is such that when the same body is kept on a perfectly smooth plane inclined at an angle, a force of 6N applied at an inclination of 30" to the plane keeps the same in equilibrium. Assume coefficient of friction between the rough plane and the load is equal to 0.3.
Determine (fg) (x) if f(x)= 5 - 2x and g(x) = 3x + 1.
