You don’t have to be a scientist to figure out that you don’t want to get in the way of a LeBron James dunk, but if you are like John Brenkus and figure out that LeBron generates 700 lbs of force during take off to lift his 250 lbs frame, his arm can move as fast as a Chinook helicopter blade and if he converted his vertical arm movement (54 mph) into a horizontal punch he would be able to hit harder than Mike Tyson in his prime. Basically, never jump in front of this train with a headband if you value your life and limbs.

Using the dunk LeBron James had on Kevin Garnett during Game 4 of the 2008 Cavs vs. Celtics contest as the beaker / poster, see the science behind “The King” crowning KG, after the jump.
