The Five Biggest Contradictions in Fitness

Itís no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?

    Simple mechanics question

    This is a basic physics question off an earlier version of an entry exam that I will have to pass for my life to have any meaning. The test has questions on biology, math, chemistry and physics. This is the first physics question, the warm-up. and either I cant even do that or there is a mistake.

    I'm concerned that the correct answer is not provided in the multiple choice.

    A sprinter has to run 100 meter.

    During the first 1.250 seconds, he constantly accelerates with 8.0 meters per second^2.

    After that his speed remains constant until the finish.

    How long does he take to run the 100 meters?


    ----------
    My answer was he accelerates by 8.0 meters per second^2 for 1.250 seconds, so after 1.250 seconds he is moving at 10 meters per second.

    his average speed during the first 1.250 seconds is 4.0 meters per second.
    so after 1.250 seconds he has travelled 5 meters, and has 95 meters to go.

    He does these 95 meters with 10 meters/second, so it takes him 9.5 seconds.

    Therefor the total time it takes him to travel the 100 meters, =
    9.5 + 1.250 = 10.75 seconds.

    -------------

    However the answers to choose from are
    A> 10.000 s
    B> 10.250 s
    C> 10.455 s
    D> 10.625 s

    And the answer model says answer D is correct.
    Did I make a mistake?
    or
    Is there really a mistake in such an important test?
    Both would be rediculous.

    Ah I got it.
    another guy explained it to me.

    The average speed during the first 1.250 seconds is 5.0 m/s, not 4
    after all the acceleration may be 8.0 m/s^2 but the speed reached is 10.0 m/s.

    This is just because we always got round numbers in HS. I'm too much of a coward to take responsibility for this one.

    Your whole personal realisation is dependent on one exam? What will you do if you fail?

    The other guy is right.

    Squats work better than supplements.
    "You know, if I thought like that, I'd never put more than one plate on the bar for anything, I'd never use bands or chains, I'd never squat to parallel or below, and I'd never let out the slightest grunt when I lift. At some point in your lifting career (assuming you're planning on getting reasonably strong and big), you're going to have to accept that most people think you are some kind of freak." -Sensei
