In real machines, efficiency is always <em>less </em>than 100% .
Mathematically we know that the position is the integral of the velocity as a function of time, that is, the general formula for determining the position as a function of velocity would be given by
Here
represents the initial position, and the integral, the position with respect to the speed of the object within a certain time
Replacing and considering that there is no starting position,
Look it up it's really easy :) I don't really remember all of this. I haven't learned about this stuff since like 7th grade
