    Re: Substitute

    In case anyone's interested, I got the answer to problem 1 to be a little under 37.5m. Problem 2 is somewhat harder.

    Re: Substitute

    Napkin maths for problem 2 implies that you'd move at an angle approx two/thirds between top raptor and a corner raptor (since corner raptors are 2.5 times as fast as top raptor)

    Re: Substitute

    Well, it got my attention more than the one about driving from Ecclesthorpe to Swindon did.

    For number 2, I think you have to assume that the raptors are smart enough to anticipate where you are going, and will head to intercept, rather than run toward you and then adjust course to follow, even though the latter case is more likely.

    it will be slightly over 2/3 to the top one

    as he can only run at 10m/s and other can run at 25m/s

    Class proof there

    I think you're all wrong. He should run straight towards the wounded raptor and kick it in the other leg on the way past

    Or he should finish off the crippling of the crippled raptor, thus giving the others something to eat so he can go free?

    Re: Substitute

    I think what Brucelles said is absolutely spot on. If the raptors were intelligent enough to come up with a straight, mathematically optimal path to intercept the little man, the problem would be doable - the position vectors are easy enough.

    But if they just ran at him and adjusted their heading as he ran they would follow a curved path, much harder to model. I believe someone managed to do it using computer algorithms, but I can't remember the link.

    Either way, the comic was meant to be a joke.

    Question, if you stood still and held your breathe, would the raptors still munch on you?
