The real question is if you slapped hard enough to raise the temperature to 74C (undergrad clearly doesn’t cook), what would the temperature of your hand be? And for the engineers: how far up your arm would you have to measure before the temperature returned to normal body temperature? And for the bio/kin/nursing/premed students: how much would need to be amputated?
That’s like… 4 or 5 times the speed of sound at sea level so… There would be a bit of a boom.
