- In tae-kwon-do, a hand is slammed down onto a target at a speed of 15.4 m/s and comes to a stop during the 4.29 ms collision. Assume that during the impact the hand is independent of the arm and has a mass of 0.770 kg. (the magnitude of the impulse is 11.9 kg*m/s) What is the magnitude of the average force on the hand from the target?
