Homework Help: What is the force exerted on the hand by the blocks?

  1. Dec 3, 2003 #1
    can someone give me the formula needed to do this problem?

    "a karate strike hits wooden blocks, the hand undergoes an acceleration of -6500 m/s2. Medical data indicates the mass of the forearm and hand to be about 0.8 kg. What is the force exerted on the hand by the blocks?"

    am i supposed to convert kg into something else???

    How about Newton's second law of motion?

    In other words: Force= mass times acceleration!
