Question 4 (20 points) =[@en [ + | A uniform ladder of length 10.0 m and mass 16.0 kg is resting against a vertical wall making an angle of 60with ground. The vertical wall is smooth but the ground is rough. An electrician weighing 60.0 kg climbs up the ladder. If he stays on the ladder at a point 8.00 m from the lower end, what will be the normal force and the force of friction on the ladder by the ground? What should be the minimum coefficient of friction for the electrician to work safely? (g= 9.81 'TTL/S2 )
