Dear Physics Professor RP,

Thanks for helping me understand f, but like any good student, I have a couple of f questions.
I was wondering the measurable f it took using your formula of course, for me to respond to your enlightening thread. To help you help me I can tell you I weigh 200 lbs. which I think converts to 90.7184 kilos give or take a zero? As far as a or acceleration, I am completely at rest at my desk, although my brain is moving as usual, ever so slowly, and or unless you take into account my motion as the earth turns, and as the earth rotates around the sun, and as the solar system spins, and as the galaxy turns, and as the universe expands. Do you count all or any of those motions to find f? If so than how many meters per second is that? Oh, and what about the time it took to respond, response time or RT, which is like you RP? Anyway, how many newtons did it take me to respond or as you say, f? For your solution to f, I'll bring you a Newton apple someday for the energy or f it took for you to respond back to me!
Thanks,
Your physics student in the back row,
