My personal understanding and opinion is that ALL of those questions
should be part of an assessment of Physical Activity Readiness.
Period = (1) / (frequency)
Period = (1) / (200 per second) = 0.005 second = 5 milliseconds
Because the act of braking is an example of negative acceleration.
Example: if the rate of braking was say 2 meters per second^2, and the starting velocity was 10 m/s, it would take 5 seconds to come to a stop(during those 5 seconds you would still be moving).
