Analyzing the work done by individuals with different strategies climbing a mountain based on their mass, time, and method – walking, climbing along a slope, or floating with helium-filled balloons. Determine the most work-efficient approach.
E N D
191. Bill, Jill, and Gill, each have a mass of 57kg. Bill climbs to the top of Moe’s Mountain in a time of 1hour by walking up slope “A”. Gill climbs the mountain in .75hours by climbing along slope “B”. Jill is a little more resourceful than Bill or Gill, she used a bunch of Helium filled balloons to float directly up the side of the mountain in .50hour. In which situation was the most work done scaling the mountain? • A. In each case the same amount of work was done. • B. Gill did the most and Jill did the least. • C. Since W=FD we need the height of the mountain to determine the work done by each. • D. Jill did the most work and Gill did the least. A. The same amount of work was done in each case because the all moved the same force through the same distance. Time is not a factor.
