So, if you are hanging to start and you need to accelerate to a velocity of 6.26m/s top make the jump. The distance over which you are accelarating is approximately the length of your arm (say 1 metre to make the maths easier). So at the beginning of that 1 metre you aren't moving and by the end you are moving at 6.26m/s. Your average velocity during this period (assuming uniform acceleration) is 3.13m/s. So it takes about a third of a second to accelerate. Therefore (once again assuming uniform acceleration) you're going from 0m/s to 6.26m/s in one third of a second so the acceleration is about 18 metres per second squared resulting in a force of 1.8 kN on the hold.
