The ground does 1600T of work to stop a falling ball in .05 M. What force is needed?

Work is defined as a displacement of an object or thing due to being acted upon by a force. The more work done, the more force is used when compared to the distance the force was done over. We can find the amount of force (measured in joules) using the equation:


`W=F/d`


Work is equal to the force applied divided by the distance. In your question, the work done to the ball is equal to 1600J (I assume you meant J and not T as T is not a unit of force). The distance here would be equal to 0.05 meters. Since we're trying to find the force done, we need to re-arrange our problem by isolating the force variable. Then we plug in our variables and find our answer.


`W=F/d`


`Wd=F`


`(1600J)(0.05m)=F`


`F=80N`


In order for the ball to stop in the given distance with the given amount of work it would have to have 80 Newtons (SI unit for force) placed upon it to bring it to a stop by the ground. I hope that helped you better understand the work equation!

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
