In a critical scene in John Woo's motorcycle-heavy second installment of the Mission Impossible series, Tom Cruise and evil Dougray Scott have a head-on showdown on their respective high-powered bikes, which ends in a midair collision after each is somehow able to leap off his bike. Neither seems particularly fazed, as the two continue to grapple apparently unhurt on the ground and for the rest of the movie.
Assuming speeds of 50 mph, a collision time of 0.015 second, and masses of 80 and 90 kilograms for Cruise and Scott, respectively, the force generated by the impact is an incredibly large 124,000 newtons, all exerted on the upper-right halves of the combatants bodies. Estimating the area of impact to be around .35 square-meters, we can solve for the amount of pressure exerted on their bodies at the point of impact: 350,000 N/m2. Putting these numbers in real-life terms (what, you don't know what one newton of force feels like?): In car-crash studies, any pressure of that magnitude on the human body results in a 50-50 chance of surviving, with those who do survive coming away with massive internal trauma. Not only do Cruise and Scott survive the initial impact, they don't appear to have even a broken bone between them, when. Iin reality, Tom would need a whole lot of nontraditional healing to recover from this one.
