6) A 15 kg uniform ladder makes 60 degrees with the
ground and a worker with 60 kg mass climbed to the top. The length
of the ladder is 1.2 meters and it is uniform. The other end of the
ladder is on a wall without friction. Draw the free body diagram
show all the forces. What should be the minimum friction
coefficient (mu) on the ground so that the ladder won’t slide.
(Calculate the Normal force of the ground, Friction on the wall and
the reaction force of the wall. Show work)
