The elastic band on a catapultis pulled back 0.6 m. If the projectile in the catapult flies forward with a kinetic energy of 439 J, what is the spring constant (in N/m) of the elastic band? Note that the kinetic energy with which the projectile flies forwards is equal to the elastic potential energy of the band just before release.
