2. Read the following experiment. Describe the experiment's results; identify which of
Newton's laws is illustrated and how these results support this law. (10 points)
A karate master can exert a tremendous force by utilizing years of training, proper technique,
and focus. Although a human hand and forearm may have a mass of 0.75 kg, with proper
technique a karate sensei (master) will be able to use his entire body's mass to break bricks.
Combining all his abilities, this master will exert 3,500 N of force, far more force than is
needed to break several bricks.
