The figure shows a 75 kg construction worker sitting on a massless beam with a length of 3.0 m. If the tension in the cable is 1100 N, how far from the left end of the beam is the construction worker sitting?
A construction worker sits on a 6.0 meter long horizontal beam, 2.0 meters from its right end. A cable extends upward and leftward at a 30 degrees angle above the horizontal from the right end of the beam to the wall.
