The unit of acceleration would be m/s² :)
Do 25-14 and you will get your answer
No, it should not be permitted. It can seriously damage one of the people participatings mind. It would overall not be good
To solve this problem we will define the order of magnitude of both points, then we will obtain the radius and obtain the conclusion of the order of magnitude.
A nanosecond is one billionth of a second while and a millisecond is one millionth of a second
Therefore something that runs in nanoseconds is six times faster than something that runs in milliseconds
