A4_6 The Penny Drops

John Coxon, Joshua Barker, Thomas Conlon


A British 1p coin is dropped from a great height. Its terminal velocity is calculated, alongside the force (and subsequently pressure) it would exert upon a surface on landing. The value is compared to the tensile strength of normal human skin in order to examine the effects it might have if it landed on a person, and is found not to be high enough to break the skin.
