How far could Elastigirl launch Jack-Jack?

Maddie Coles


Elastigirl from ‘The Incredibles’ has superhuman elasticity, amongst other special powers. This elasticity could enable her to act as a catapult and launch different objects considerable distances. This paper determines that Elastigirl’s elastic potential energy, when fully stretched, is 17000 J. This is converted to kinetic energy and transferred to Jack-Jack, and would allow the super-baby to travel a distance of 255 m in the air before landing, if launched at a 45° angle.
