assuming you really want that order and it is not a typo
To rank the objects in terms of air drag from highest to lowest, follow this order:
1) A 10lb styrofoam block traveling faster than terminal speed
This object will experience the greatest air drag because it is both heavier and moving faster than its terminal speed.
2) A 10lb styrofoam block at terminal speed
Although this object has the same weight as the previous one, it is not traveling faster than its terminal speed, resulting in slightly less drag.
3) A 5lb lead block traveling at 95% terminal speed
Despite being a heavier object, the lead block is traveling close to its terminal speed, which reduces the air drag as compared to the previous two objects.
4) A 5lb styrofoam block at terminal speed
This object will experience the least air drag since it is both lighter and at terminal speed. Styrofoam is much less dense than lead, leading to a lower drag force.
Therefore, the ranking from least air drag to greatest air drag is as follows:
2nd least air drag: A 5lb styrofoam block at terminal speed
Least air drag: A 5lb lead block traveling at 95% terminal speed
2nd greatest air drag: A 10lb styrofoam block at terminal speed
Greatest air drag: A 10lb styrofoam block traveling faster than terminal speed
To rank the options in order from least air drag to greatest air drag, we need to consider the characteristics of each scenario and understand the factors that influence air drag.
Air drag is influenced by several factors, including the size, shape, and speed of an object. Typically, objects with larger surface areas and less streamlined shapes experience greater air drag, while objects with smaller surface areas and streamlined shapes experience less air drag. Additionally, higher speeds generally result in increased air drag.
Now, let's analyze each scenario to determine their ranking:
1) A 5lb lead block traveling at 95% terminal speed:
Since lead is a dense and heavy material, it has a larger surface area and is less streamlined compared to other materials. Traveling at 95% of terminal speed indicates that it is not at its maximum velocity. Therefore, it experiences less air drag compared to higher speeds. However, due to its material properties and shape, it still experiences considerable air drag. This scenario will be ranked as the 2nd least air drag.
2) A 5lb styrofoam block at terminal speed:
Styrofoam is a lightweight and porous material, which means it has a lower density and smaller surface area compared to lead. Its shape is also likely to be more streamlined. At terminal speed, which is the maximum velocity an object can reach in free fall due to gravity and air resistance balancing out, the styrofoam block experiences some air drag, but less than the 5lb lead block. This scenario will be ranked as the least air drag.
3) A 10lb styrofoam block traveling faster than terminal speed:
Similar to the previous scenario, the 10lb styrofoam block still has the advantages of being lightweight and having a streamlined shape. However, it is traveling faster than terminal speed, which means it is experiencing increased air drag compared to lower speeds. Although it's still a styrofoam block, the higher speed results in greater air drag. This scenario will be ranked as the 2nd greatest air drag.
4) A 10lb styrofoam block at terminal speed:
Finally, the 10lb styrofoam block at terminal speed is similar to the previous scenario in terms of material and shape characteristics. However, it is not traveling faster than terminal speed, so its air drag is expected to be slightly lower. Although both styrofoam blocks have relatively low air drag compared to other materials, this scenario will be ranked as the greatest air drag.
Based on the analysis, the ranking from least air drag to greatest air drag is as follows:
2nd least air drag: 5lb styrofoam block at terminal speed.
Least air drag: 5lb lead block traveling at 95% terminal speed.
2nd greatest air drag: 10lb styrofoam block traveling faster than terminal speed.
Greatest air drag: 10lb styrofoam block at terminal speed.
