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???

In other words: Force= mass times acceleration!
