Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A weight (with a mass of 28 kg) is suspended from a point on a uniform boom whose mass is unknown. To support this boom, a cable (with a tension of 338 N) runs from this same point on the boom to a point on the wall (with vertical coordinate at a height of 10 m) and a pivot is on its lower end (at the origin of the coordinate axes). 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 VerticalHeight(m) Horizontal Distance (m) M b 3 3 8 N 28 kg Figure: Drawn to scale.
