 . It takes the raptor 25m/s / 4m/s^2 = 6.25s to reach it's top speed, during which I can run 6.25s * 6m/s = 37.5m.  Add on my 40m head start, and I can reach a spot 77.5m away from the raptor before he gets me.  In the same time, the raptor can run 4m/s^2 * (6.25s)^2 / 2 = 78.125m.  I'm eaten before he's fully up to speed.

 BTW, the answer to question #2 is: run straight toward the injured raptor.  The uninjured raptors will run toward you and the injured raptor.  Just as you get close to the injured one, slide under his legs.  Because he is injured, the uninjured raptors will feast on him instead of you.

 I don't think there is enough information to solve the second problem, because you don't know how fast the non-injured raptors go. Unless you take that information from the first problem. But then, how fast does the wounded raptor accelerate? You would have to find the angle where the wounded and the closest non-wounded raptor would meet you at the same time.

-With all three raptors and you running at top speeds, I don't think you get caught by the injured raptor and uninjured raptor at the same time.  I believe that you must run directly towards the wounded raptor and the two non-injuried raptors will reach you simultaneously before you and the injured raptor meet, and you cannot do better.  After all, you can try to run directly away from an uninjured raptor, but you will lose ground to it at a rate of 25-6=19 m/s (but, it is worst for the other uninjured raptor).  By running directly at the injured raptor, you lose ground from it at the rate of 10+6=16 m/s.  However, if you can accelerate at a rate far above the raptors, I think you could change directions so fast that one raptor could not catch you.  However, I am not sure you can keep away from all three indefinitely. --DrMath 04:01, 24 October 2013 (UTC)

 I did the math and if you run directly towards the wounded raptor it will catch you before the uninjured raptors do. (It would be better to run directly away from the uninjured raptor than it would be to run towards it, but that still not the answer.) As you would cover ~8m if you ran at the wounded raptor and survive for ~1.33s where as the uninjured raptors (assuming they rundirectly towards the point you meet the wounded raptor would take ~2.9s to reach this point.

 For 1 and 2 the solution depends on whether the raptors can accelerate at 2m/s, or they actually increase their speed at this rate. If they just accelerate, It should be possible to do tight circles, and even wind yourself slowly towards another location. I believe this is possible even treating yourself and the raptors as point masses. [[Special:Contributions/2.102.215.18|2.102.215.18]] 13:19, 17 July 2013 (UTC)

 There is a problem with the test, as Mr. Munroe wrote it: Question #1 says that a raptor has a top speed of 25 m/s, but question #3 says "Remember, raptors run at 10 m/s...".  Furthermore, question #2 says an injured raptor runs at 10 m/s.
