1. 5 milliseconds squared:
* This is a very small unit of time squared. It's not a common unit, but it could arise in some specific calculations related to acceleration or change over time.
2. 5 meters per second squared:
* This is a unit of acceleration. It means that something is changing its speed by 5 meters per second every second. This is commonly used in physics to describe how gravity affects objects.
3. 5 minus 2 milliseconds:
* This would simply mean 3 milliseconds. However, the "ms" would typically be written before the numbers in this case (i.e., 3 ms).
To understand the meaning, you need more context. For example, where did you see "5ms-2"? What was the surrounding text or equation?
Please provide more information so I can help you understand the intended meaning.
