The diagram below represents an elevator used to lift concrete blocks to upper levels on a construction site. The belt travels at a velocity of 0.9 m/s and is inclined at 26° above the horizontal plane.

A sled of mass 500kg sits at rest on a rough slope that is inclined at 10* to the horizontal. The coefficient of friction between the slope and the sled is 0.3. The sled is held in place by a wire attached to a winch. The tension in the wire is TN. a) Find the maximum possible value of T.   A load of mass mkg is added to the sled, and tension in the wire is increased to 5000N in order to pull the sled and load up the slop. Given that the sled and load are pulled a distance of 100m in 80seconds, b) Work out the value of m
